Find the slope
Find the slope of the line containing the points (-9, 1/2) and (-5, 1/2)

Since the points have the same y coordinate the slope of the line is zero.

Use the slope formula.

$m=$ slope

$m = \frac{\left(y_2-y_1\right)}{\left(x_2-x_1\right)}$

where $\left(x_1,y_1\right)$and $\left(x_2,y_2\right)$ are distinct points on the line

Thanks everyone: I think I have it:

Using the point slope formula
m=(y2-y1)/(x2-x1)
m=([1/2]-[1/2])/([-5]-[-9])
m=0/4
m=0
with a slope of 0
m=rise/run
