Question

If AD is the altitude to BC, what is the slope of AD?

A. −4/3
B. −3/4
C. 4/3
D. 3/4

Answer 1

-4/3

Explanation:

Before we can get the slope of AD, we need to get the coordinate of point D.

D(X, Y) = (5-3/2, 5-1/2)

D(X, Y) = (2/2, 4/2)

D(X, Y) = (1, 2)

Next is to get the slope of line AD

Slope = y2-y1/x2-x1

Slope= -2-2/4-1

Slope of AD = -4/3

Hence the slope of AD is -4/3
