Question

A) 9 B) 0 C) Undefined D) 6

Answer 1

Answer:

B) 0

Step-by-step explanation:

The slope of a horizontal line is equal to 0.

The slope of a vertical line is undefined.

The formula of a slope:

$m=\dfrac{y_2-y_!}{x_2-x_1}$

Put the coordinates of the pojnts from the graph (2, 9) and (4, 9):

$d=\dfrac{9-9}{4-2}=\dfrac{0}{2}=0$
