Question

Find the slope of the line perpendicular to AB. A(3, 5) and B(3, -8).

Answer 1

m = 0

Explanation:

AB has a slope of y2 - y1 / x2 - x1 so -8-5/3-3 so -13/0 = undefined so it is a vertical line, so any line that is horizontal will be perpendicular to it, so horizontal lines have a zero slope
