-7 (APEX)
The slope is -2/3.
The slope of a line perpendicular to one with slope m is -1/m. So for a line with slope 1/7, any line perpendicular to it will have: slope = -1 / (1/7) = -7
1/7
Points: (1, -1) and (5, -7)Slope: -3/2
Points: (-3, -1) and (-7, -8) Slope: (-1--8)/(-3--7) = 7/4 or 1.75
Points: (-1, -11) and (-6, -7) Slope: -4/5
Points: (1, 7) and (-3, 2) Slope: 5/4 or 1.25
-7
Points: (7, -1) and (-2, -4) Slope: 1/3
Points: (-3, 5) and (1, 7) Slope: 1/2
Points: (-3, 5) and (1, 7) Slope: 1/2
y = x - 7 or, y = 1*x - 7 so that the slope is 1.
slope = difference_in_y/difference_in_x = (-1 - -7)/(3 - 1) = 6/2 = 3
