Find the slope of the 2 points
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
m=%28-4-5%29%2F%28-3-0%29
m=-9%2F-3
m=3
To find the perpendicular line invert and negate the slope we just found. In other words
m%5Bp%5D=-1%2Fmwhere m%5Bp%5D is the perpendicular slope
So m%5Bp%5D=-1%2F3
So the slope of the line perpendicular to the line going through (0, 5) and
(-3, -4) is m=-1/3.
