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

-4/3

Step-by-step 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

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

cosine
