3/7
y-4=3/2(x-7)
Slope = [(-2) - 3]/(7 - 4) = -5/3

Slope of the given line is 3/7 So slope of perpendicular line is -7/3
3/7
y-4=3/2(x-7)
Slope = [change in y]/[change in x] = [3 - 2]/[7 - (-1)] = 1/8
(2,4) (1, -3) First, find the slope, which is change in y over change in x. from -3 to 4 is 7 from 1 to 2 is 1 The slope is 7. Using the point slope formula you can find it in slope-intercept form. point-slope is y-y1=m(x-x1) *Number 1's are subscripts and m=slope* [You use a point for y1 and x1] y- (-3) = 7 (x-1) y+3 = 7x - 7 y= 7x -10
-1/4
Points: (7, 3) and (5, 9) Slope: -3
Slope = [(-2) - 3]/(7 - 4) = -5/3
Points: (0, 0) and (7, -t) Slope: -3/5 Slope = 0--t/0-7 = -3/5 - t/7 = -3/5 Multiply both sides by -7: t = 21/5 or 4.2
Points: (7, -3) and (-7, 4) Slope: (-3-4)/(7--7) = -1/2 or -0.5

The slope is the change in y divided by the change in x ("rise over run"). For the points (x1, y1) and (x2, y2), the slope calculation is: ( y1 - y2 ) ( x1 - x2 ) For the points (3, -9) and (7, 6), the slope calculation is: ( -9 - 6 ) = ( -15 ) = 3.75 ( 3 - 7 ) ( -4 )
Points: (-3, -10) and (5, -7) Slope: 3/8
