y-coordinates of the points are same.

So, line is parallell to x -axis, and line equation is y = 8

Horizontal lines slope is zero.

Slope of the line containing these points is zero.

 

Let's check the same with slope formula.

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

Let (x1, y1) = (4, 8) and (x2, y2) = (-2, 8)

Slope, m = ( 8- 8 ) / (-2 - 4)

Slope, m = 0/ -6

Slope, m = 0

If slope is is zero the line is horizontal line.

Slope of the line containing the points (4,8) and (-2,8) is 0.
