To calculate the slope of a line that goes between two points, you need to divide the difference in y-coordinates, by the difference in x-coordinates. In this case, hte calculation would be:
(2 - (-4)) / (3 - 0)
Points: (3, -2) and (0, 4) Slope: -2
Points: (-2, -3) and (4, 0) Slope: (-3-0)/(-2-4) = 1/2
slope = change_in_y / change_in_x = (2 - -4) / (3 - 0) = 6/3 = 2
Points: (5, 0) and (3, -4) Slope: 2
Points: (-3-2) and (4, -2) Slope: (-2--2)/(-3-4) = 0
Points: (3, -2) and (0, 4) Slope: -2
Points: (-2, -3) and (4, 0) Slope: (-3-0)/(-2-4) = 1/2
Points: (0, -1) and (-2, -4)Slope: 3/2
Slope: (2-4)/(0--3) = -2/3 Perpendicular slope: 3/2
slope = change_in_y / change_in_x = (2 - -4) / (3 - 0) = 6/3 = 2
Points: (5, 0) and (3, -4) Slope: 2
Points: (5, 0) and (3, -4) Slope: 2
Points: (-3-2) and (4, -2) Slope: (-2--2)/(-3-4) = 0
The slope of the line joining the two pints is (4 - 2)/(-3 - 0) = -2/3 Therefore the slope of the perpendicular is 3/2
If you mean points of (0, 4) and (4, -2) then the slope is -3/2
-2/3
m(slope = Y2 - Y1/X2 - X1(0, 4) and (4, - 2)m = - 2 - 4/4 - 0= - 6/4= - 3/2======
