Points: (3,-1) and (-2, -5) Slope: 4/5
Points: (-3, 1) and (2, 4) Slope: (4-1)/(2- -3) = 3/5
Points: (5, -1) and (2, -5) Slope: 4/3 Perpendicular slope: -3/4
let (2,-5) be P1 and (-1,-8) be P2 Slope is -5+8/2+1=3/3=1
Points: (2, -6) and (-3, 1) Slope: (-6-1)/(2--3) = -7/5 or -1.4
Points: (1, 7) and (-3, 2) Slope: 5/4 or 1.25
slope=(2-1)/(3-5)=-1/2
Points: (1, 3) and (3, -2) Slope: -5/2 or -2.5
Points: (-3, 5) and (6, -1) Slope: (5--1)/(-3-6) = -2/3
Points: (1, -2) and (3, -5) Slope: -3/2
Points: (2, -3) and (5, 1) Slope: (-3-1)/(2-5) = 4/3
Points: (3,-1) and (-2, -5) Slope: 4/5
Points: (-3, 1) and (2, 4) Slope: (4-1)/(2- -3) = 3/5
slope = change_in_y/change_in_x = (2 - 5)/(0 - 1) = -3/-1 = 3
Points: (-1, 2) and (4, 3) Slope: 1/5
slope = change_in_y / change_in_x = (5-2) / (3-1) = 3/2 = 1.5
Points: (5, -1) and (2, -5) Slope: 4/3 Perpendicular slope: -3/4
