How can i find the slope intercepts of a line the problem is Y=-5x-17 ?

Remember the slope-intercept form?\n\ny = mx + b.\n\ny = the y coordinate.\nx = the x coordinate.\nm = the slope.\nb = the y - intercept.\n\nyour equation is already in slope-intercept form. so all you need to do is match up your numbers with the y = mx + b.\n\nThe slope is -5.\nThe y - intercept is -17.\n\nHope that helps :)

Problem 1: Find an equation for the line with y-intercept 3 that is perpendicular to the line y=2/3x-4\n\nto find a line perpendicular to another line, use the opposite reciprocal of the slope\nin this case, the slope is 2/3, therefore the opposite reciprocal of the slop is -3/2\nnow you know the slope and you also know that the y-intercept is 3\nuse the equation y = mx + b\nif m is the slope and b is the y-intercept, then your equation is\n\ny = (-3/2)x + 3\n\n-------------------------------------------\n\nProblem 2: If P(4,-5) is a point on the graph of the function y=f(x), find the corresponding point on the graph of y=2f(x-6)\n\ny = 2f(x-6)\ny/2 = f(x-6)\ny = -5\nx = 4\nplug them into the equation\n-5/2 = f(4-6)\n-5/2 = f(-2)\nx = -2\ny = -5/2\n\nthus the answer is\nx = -2\ny = -5/2\nhaving trouble with this one myself... sry... dont know the answer

Solve for y: y=3x\n\nThe slope is 3, and the y-intercept is (0,0). (y=mx+b: m is slope, b is y-intercept)\n\nThe slope is the change of y over the change of x.\n\nStart from (0,0) and go up 3 units, right 1 unit.  Connect the points and continue the line.

slope intercept formula is y=mx +b to find b subsitute in for y,m, and x.  so 1 = -2(0) + b.   1 = 0 + b so b = 1 then your equation would be y=-2x + 1.

slope equals rise/run. slope=4 y-intercept=-20

Remeber that perpendicular lines have negative reciprocal slopes, so the slope of the line you are trying to find is 1/3 (that is the negative reciprocal of -3).  You know that the y intercept is 5, remember that slope intercept form is y = mx + b where m is slope and b is y intercept.  You know both of these things now, the m = 1/3 and the b = 5.  Your equation is y = 1/3x + 5.

You don't need a calculator at all. 7/2=3.5\nFirst you need to find the slope of the line with the formula m=(y2-y1)/(x2-x1)\nso slope m=(-5-(-3))/(3.5-.5)=-2/3\nThen we need to find y-intercept by plugging info into slope intercept form y=mx+b\n-3=-2/3(.5)+b\nb=-3 + 1/3\nb=-2_2/3\nso equation is y=-2/3 x -2_2/3

slope of the second line is  3/2  ( y=3/2 x - 5 )\n\nso slope of the 1st line -2/3\n\ny=-2/3 x + b, plug in ( 2, -1) to solve for b\n\n-1 = -4/3 + b\n\nb=1/3\n\nso eq of the first line is y=-2/3 x + 1/3\n\n or                                  3y=-2x + 1

You have 2 points, (x1,y1) and (x2,y2) and you want to find the equation of the line that goes through these points.\n\nThe first thing you want to do is find the slope.\nslope is rise/run so m = (y1-y2)/(x1-x2)\n\nFor slope intercept form , y = mx + b\nwhere m is the slope, and b is the y intercept\nnow that you have found the slope, you can solve for b, the y intercept by plugging in your value for m and one of the given points, either (x1,y1) or (x2,y2).\n\nFor point slope form,  y - K = m(x - H)\nm is the slope, and   (H,K) is a point that the line passes through.\nSince you have already calculated the slope, m, for the slope intercept form, you're already almost done. All you have to do is plug in the point (x1,y1) or (x2,y2). In your question, you are asked for the point slope form of just point (6,2).

Where x = 0, the line intercepts the y-axis:\n\n1. 5x-2y =10 \n2y = 5x - 10\ny = (5/2)x - 5 \ny-int = (0, -5)\n\n2. 2y+7x =14\n2y = -7x + 14\ny = (-7/2)x + 7\ny-int = (0, 7)\n\n3. x=3\nHas no y-intercept\n\n4. 1/2x-2y=8\n2y = (1/2)x - 8\ny = (1/4)x - 4\ny-int = (0, -4)

Hopefully you know how to solve one part of it. Slope intercept form is Y= M x+B. First find the slope, using 2 set of coordinates, that formula is Y2-Y1 over X2-X1. that will be your M.  Then find your Y intercept. then plug it in to that formula above. I hope i was of some help. Don't put your life on this i did it in the beginning of the school year.  I may have the M and the B switched.

Well done, you have already done the hard work. The number in front of the x is the slope ie -2/13 and the other number is the y co ordinate of the y intercept ie (0 , 5/13). Another way to find the y intercept is to substitute zero for x and solve for y, or alternately substitute zero for y to find the x intercept.

use the slope formula.\n\ny sub 2 minus y sub 1 divided by x sub 2 minus y sub 1\n\nthen you get 1-5 divided by 0-2\n\nthen you get -4 divided by -2\n\nthe answer is 2

Well, first, write it in standard form (y=mx+b).\n\ny = -3x + 0\n\nThe m in the equation is the slope of the line, and the b is the y-intercept. \n\nSlope = -3\ny-Intercept = 0\n\nFor another example, y = 5x + 3 would have a slope of 5 and a y-intercept of 3.\n\n\nHope this helped.

y = x^2-5x\n0 = x^2-5x\n\nx^2-5x = 0\n\nx(x-5) = 0\n\nx = 0 or x = 5\n\nx-intercepts : (0,0) and (5,0)\n\nANSWER : two

If you plot those two lines, the solution is the place where they cross each other (if they do)... but.. let's set them up in Slope-Intercept form:  y = mx + b, where m is the slope and b is the y-intercept.\n\n-6x - 7y = 65 ==> y = -(6x +65)/7 ==> y = -(6/7)x - 65/7\n\n4x + 3y = -35 ==> y = (-4x -35)/3 ==> y = -(4/3)x - 35/3\n\nsince the slopes are different, the lines WILL cross and there is only 1 solution (if they had been the same slope then either there would have been no solution or infinite solutions)\n\none way to find the solution.. \n\n-6x -7y = 65 ==> multiply equation by 2 ==> -12x -14y = 130\n4x + 3y = -35 ==> multiply equation by 3 ==> 12x + 9y = -105\nnow add the two equations to eliminate x ==> 0x -5y = 25\nor... solving -5y = 25 for y... you get y = -5\n\nnow plug this value into one of the equations and solve for x:\n\n4x + 3(-5) = -35 ==> 4x - 15 = -35 ==> 4x = -20 ==> x = -5\n\nso your solution is (-5, -5)

Standard form for a slope intercept equation is:\n\ny = mx + b\n\nwhere m is the slope and b is the y-intercept.  So, transforming:\n7x + 4y = 20\n4y = 20 - 7x\ny = (20 - 7x) / 4\ny = 5 - 7/4 x\ny = -7/4 x + 5\n\nAnd\n5x + 6y = 19\n6y = 19 - 5x\ny = (19-5x) / 6\ny = 19/6 - 5/6 x\ny = -5/6 x + 19/6
