Question 88074: Refer to Example 5 and 6 (p 622) in your text for Problems 16 and 20. The key is to find the slope of the line between the two given points, then use that value to determine the slope of a perpendicular line.

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
