The slope of a line is the change in the y coordinate divided by the change in the x coordinate.

In your case, there is no change in the y coordinate, so the slope is zero. It is a horizontal line

Slope is rise over run. So take the change in y over the change in x. [-4 - (-4)] / [-1 - 8] = 0/-9 = 0. So the slope is zero.

y2-y1/x2-x1 = m

(-4- -4)/ (8 - -1) = 0/9 = 0

m = 0
