give an equation for line that passess through the point (7,5) and has an undefined slope?

Well, you need two points to define a line (or one point and a slope).  There are infinitely many lines through the point (7,5).  So just pick one:\n\ny=x-2\ny=2x-9\ny=3x-16\ny=4x-23\n...

ok so the standard equation of a line is y = mx + b, so you want to get the second equation into that form:\n\n5y = 12- 3x\ny= 12/5-3/5X\nso the slope here is -3/5\n\nfor the set of two points:\nthe equation for a slope is (y2-y1)/(x2-x1) so:\n(7-3)/(4-2) = 4/2\n\nso 2 is greater than -3/5 therefore, the slope of the first line is larger

It will look like a < with lines of slope 1 and -1.  The leftmost point will be at (0,-1).

slope = (-4-(-6))/(-2-0)\nslope = -1

Let the 2 points be (x1,y1)  and  (x2,y2)\n\neqn of line s given by\n\n(y-y1)/(y2-y1) = (x-x1)/(x2-x1)\n\nwhere  (y2-y1)/(x2-x1) is the slope of line

slope= mx+b\nslope=1/2x\nequation= y=1/2x-3.5\ny-int: -3.5

3x - 5y = 7\n5y = 3x - 7\ny = (3/5)x -7/5\nA line parallel to it is y = (3/5)x + b\n(6 , -7) on it, so -7 = (3/5)*6 + b\n-35 = 18 + 5b\n5b = -53 and b = -53/5\nThe wished line is y = (3/5)x - 53/5 or\n5y = 3x -53\n\nTh

It has no y intercept cuz its a vertical line.\nIt's slope would be undefined cuz when you try to find the slope the normal way using two points, say (-7,4) and      (-7,8), the slope would be (8-4)/(-7-(-7))=4/0 which is undefined

If the equation is lineear, or a line like it sounds like, the equation is y=mx+b. m is the slope or ten. and b is the y-int. or -130, and you are done

slope = (-1-2)/(-1-0) = -3/-1 = 3

~this is a horizontal line\nand the equation is x= -5

slope = (y2-y1)/(x2-x1)\n5= (k-4)/(2-3)\n5= (k-4)/(-1)\nk-4= (-1)*5\nk-4= -5\nk= 4-5\nso k= -1.\ni hope you understand they way I worked it out. If you have any more questions, pls feel free to ask me on: pinkieflava@yahoo.co.uk

Point slope form:\n\ny-(-3)=(1/2)(x-5)

if a line has the equation px+qy=r\nthen the slope of the line is -q/p

I hope this helps you solve these types of problems. \nThere is only one straight line that you can draw that passes through both points. The equation of this line will be in the form y = mx + b where m is the slope (rise/run) and b is the y "intercept"(the value of y when x = 0) \nTo find the equation you must find both m and b.\nm = rise/run \nThe rise is the difference between the values of y for the two points = 1 - (-6) = 7\nThe run is the difference between the values of x for the two points = 3 - (-2) = 5\nSo the slope m = 7/5.\nSo we have y = (7/5)x + b. But we still need to find b.\nTo do this, you plug in the values of x and y for either one of your two points. We'll use 3,1. So we have:\n 1 = (7/5)3 + b and so b = 1- (21/5) = -16/5. This means the line crosses the y axis at y = -16/5\nWe now have the equation to the line:\ny = (7/5)x - 16/5

see ill do one sum for you . based on those lines u can do the others.\n\nfirst find the slope of the line\n\nslope  m is given by the equation \n\n m = (y2-y1)/(x2-x1)\n\nhere (x1,y1) = (35,30) \nand  (x2,y2) = (155,-378)\n\n m = (-378 - 30)/(155 -35)\n\n  m = -17/5\n\nEquation of a line is of the form \ny = mx +c \nwhere x and y are the coordinates and m is the slope amd c is the constant\n\nif a line has to pass through the points (35,30) and (155,-378) then these points also must satisfy the equationof the line of the form \ny= (-17/5)*x + c\n\nto find the constant c we substitute any one of the pair of the points that has been given and then we check the answer with the help of the other pair of points given. \nCLEAR SO FAR. GOOD  Lets proceed\n\nLets use the tougher of the pair\n(155,-378)\n-378 = (-17/5)*155 +c\n-378 =   -527 +c\nso c = 527- 378 \n        = 149\n\nso the equation of the line is \n\n y = (-17/5)*x + 149 \nlets simplify it further\n\n5y = -17x + 745\n\nso the equation of the line is \n\n  17x + 5y = 745  \nTHIS IS YOUR REQUIRED ANS\n\n  to check simply substitute the value of th eother pair \ni.e. (35,30)\n\n  17*35 + 5*30 = 745\n 595 + 150 =745\n 745 = 745 \nLHS = RHS \ntherefore the equation of the line is correct.\n\nOK now use the same method to solve the otherss. all the best.

slope= 1   y-int=0\nThis is an equation. You can cancel the -7 and you'll have y=x. If you remember from the equation y=mx+b, then you'll see that here your m=1 and your b=0
