Question

What is the slope of the line that passes through the points (3, -2) and (9, -2)?

A. -3
B. 0
C. 3
D. undefined

Answer 1

the answer is B. 0
when it’s a straight horizontal line, the slope is always going to be zero. It’s only going to undefined if the line is vertical.

Answer 2

B) 0

Explanation:

m=(y2-y1)/(x2-x1)

m=(-2-(-2))/(9-3)

m=(-2+2)/6

m=0/6

m=0
