Answer

$0$

Work Step by Step

RECALL: $\text{slope} = \frac{\text{change in y}}{\text{change in x}}$ The points on a horizontal line have the same y-value. This means that for any two given points, the change in y-value is 0. Since the numerator of $\frac{\text{change in y}}{\text{change in x}}$, for whatever value of the denominator (except 0), the slope will always be equal to 0. Thus, the slope of a horizontal line is 0.
