Answer:
B)
Step-by-step explanation:
The slope of the line parallel to x-axis is zero.
(3,-6) and (7,-6) have same y-coordinates. So, this line will be parallel to x-axis and slope will be zero
B. (3,-6) and (7, -6)
The line that passes through these points is parallel to the "x" axis so it has no slope (m=0)
Hope this helps
