What is the coordinates of a point one one side of the world straight through to the other side?

Assuming your point of origin has the coordinates of y latitude N/S and x Longitude E/W, the opposite point would be y latitude S/N (The opposite direction. If origin is north, then the opposite would be the same value south.) The Longitude is figured by subtracting 180 degrees from the origin's value, and drop the minus sign, then changing the direction from east to west, or west to east.\n\nIf this does not make sense, post a detail, and I will try to clarify.

************************************************************\n\nLongitute or 'meridians' are imaginary lines that run from the north pole to the south pole. Or maybe South to north...hmmm...I'm not sure which way....I suppose if you're in the north....but then.......Oh! Nevermind that. The point: These lines measure time and distance for east and west on the globe. Remember they run north and south. They resemble an orange with it's slices running up and down. Each line between the orange slices would be a longitude line. There is 24 primary longitude lines that are 60 minutes apart. They can be broken down into minutes, degrees, and seconds but thats probably more than you are needing to know about right now. The Prime meridian where the time begins, or where the zero/24 begin and end, is called zero point of longitude or universal prime meridian. Check out any globe of the earth and you will most likely find the Prime Meridian somewhere over Europe in Greenwich.\n\nLatitude goes the other way. They are parallel lines (lines that are equally distanced from one another at any point of the lines) that run east and west but measure distances north and south of the equator. They also run parallel with the equator. So, like the equator that runs all the way around the world without touching another latitude line, the others do as well. Each circle or ring, get smaller and smaller the further north or south you go.\n\nLines of latitude intersect with lines of longitude at points on the globe and are used to specifically  locate points on the globe. These are measured generally in degrees, but, as mentioned earlier, can be broken down even further. My city, for example, is 39 degrees north and 95 degrees west. I've included a website that you can check your own city's location and time among other information. Just enter your city name and press enter.\n\nI hope this is helpful. Good luck.\n\n*************************************************************

considering both y values are -2 for A and C....\n\nwe know that a straight line exists between these two points, which means that it HAS to be 1 of the 4 sides.\n\ngiven that, the coordinates or K and L HAVE to be (3, infinity (EXCEPT -2)) and (-4, infinity (EXCEPT -2))

I think you would find a Mercator projection of the map. It shows true direction even if the shape of the land mass is distorted.

You would be at 40 46.12'S, 106 41.52'E which is in the Indian ocean. The closest land mass is 700 Miles North East (Western Australia).  \n\nThere is almost Nothing near this location but water. \nPerhaps an uncharted Island?\n\nCheck it out with google earth.\n\nYou can use the measure tool to find the point where the straight line will ROTATE like a spinning compass because the line always shows the shortest distance.\n\nAs the crow flys (or swims in this example), these two points are 12,414.94 Miles Apart.

No way to know.  What is the shape of "everything"?  I think it is round and that if you go to one end, you'll end up back at the same point if you keep going the same direction.\n\nGood question.

Find the coordinates of the points where the straight line meets 'y=1' meets the circle 'x^2+y^2-14x+2y+45=0'.\n\n'x^2+1^2-14x+2(1)+45=0\nx^2 -14x +48 = 0\nthe solutions are:\nx=(14 +- sqrt( 14^2 -4(48) ) /2\nx=14+- sqrt(4) )/2\nx= (14 +2)/2 or x= (14-2)/2\nx=8 or x = 6\n.

Astronomers generally use either the equatorial or ecliptical reference frames. The standard reference plane for the equatorial reference frame is the earth's equator. The standard reference plane for the ecliptical reference frame is the plane of the earth's orbit around the Sun. The intersection of these two planes is a line that points in one direction towards the vernal equinox, and in the other direction towards the autumal equinox.\n\nIn both systems, the zero point of longitude (for ecliptic) or Right Ascension (for equatorial) is defined as the direction of the vernal equinox, also called the First point of Aries.

x-coordinate: Count the horizontal distance from the origin (0,0).  If the point is to the right, then the number is positive.  It the point is to the left, then is is negative.\n\ny-coordinate: Count the vertical distance from the origin (0,0).  If the point is to above, then the number is positive.  It the point is to below, then is is negative.\n\nThen list them as an ordered pair (x,y)

1 degree west. Did you screw up your question?\nShouldn't you have a north or south in there?

15 degrees.  If you look at timezones they pretty well match up with 15 degrees of longitude.

International date line, located in the Pacific Ocean.  It's not a specific longitude, but drawn, I think, to miss any islands.\n\nThe International Date Line is the imaginary line on the Earth that separates two consecutive calendar days. That is the date in the Eastern hemisphere, to the left of the line, is always one day ahead of the date in the Western hemisphere. It has been recognized as a matter of convenience and has no force in international law.

The orthocentre of a triangle is the point where all the altitudes meet\n\nSo if you have ΔABC one altitude is the line through A perpendicular to BC, another is the line through B perpendicular to AC and the last is the line through C perpendicular to AB\n\nUse these facts with the coordinates of A, B, and C and the slopes of AB, AC and BC (Find where two altitudes meet and if you are correct that point will also lie on the 3rd altitude)\n\neg Find the orthocentre of the ΔABC where A ≡(1, -3), B ≡(-1, -5), C ≡(3, 1)\n\nSlope AB = Δy/Δx\n= 2/(2) \n= 1\n\nSlope of perpendicular = -1 (-1 * 1 = -1)\nAltitude to AB goes through C\nSo equation of altitude of form y = -x + b\n(3, 1) lies on altitude\nTherefore 1 = - 3 + b\nb = 4\nThus altitude through C is y = -x + 4\nie x + y = 4 ............... (1)\n\nSlope AC = Δy/Δx\n= 4/2\n= 2\n\nSlope of perpendicular = -1/2 (2 * -1/2 = -1)\nAltitude to AC goes through B\nSo equation of altitude of form y = -1/2 x + b\n(-1, -5) lies on altitude\nTherefore -5 = -1/2 * -1 + b\nb = -11/2\nThus altitude through C is y = -1/2 x - 11/2\nie x + 2y = -11 ............... (2)\n\nSlope BC = Δy/Δx\n= 6/(4) \n= 3/2\n\nSlope of perpendicular = -2/3 (3/2 * -2/3 = -1)\nAltitude to BC goes through A\nSo equation of altitude of form y = -2/3 x + b\n(1, -3) lies on altitude\nTherefore -3 = -2/3 * 1 + b\nb = -7/3\nThus altitude through C is y = -2/3 x - 7/3\nie 2x + 3y = -7 ............... (3)\n\nie we have:\n x + y = 4 ................. (1)\n x + 2y = -11 .................. (2)\n2x + 3y = -7 ............... (3)\n\nEquation (2) - equation (1)\ny = -15\nFrom equation (1) x = 19\n\nCheck in equation (2) \nx + 2y = 19 + -30 = -11 YESSSSSSSSS!!!!!!!!!!!!!\n\nCheck in equation (3) to ensure that this point lies on this altiude also\n2x + 3y = 38 + -45 = -7 YESSSSSSSSS!!!!!!!!!!!!!\n\nSo the orthocentre of ΔABC is (19, -15)

Dudes, the eqeator or prime meridian do NOT go THROUGH the center of the earth AT ALL!\n\nThe answer is Axis, duh.
