Question

What is the slope of the line that passes through the points (-4,0) and (2,0)

Answer 1

Line passing through these point will have slope = 0
as y coordinate is 0 for both points
slope = (y2-y1)/(x2-x1)=
(0-0)/(-4-2) = 0

Answer 2

Slope = (y2 - y1) / (x2 - x1)
Slope = (0 - 0) / (2 --4)
Slope = (0) / (6)
Slope = 0
