Question 88074
Find the slope of any line perpendicular to the line through points (0, 5) 
and (-3, -4).

Slope of the line passing through the points (0, 5) and (-3, -4).

Slope = (-4 -5)/(-3-0)

=-9/-3 = 3


Now let the slope of the line perpendicular to this given be m.

Then m*3 = -1

Divide by 3

m = -1/3
