The slope equals 0
This is a horizontal line through $y=-3$

Slope which is the change in $x$ versus the change in $y$ .

Slope is identified by the letter $m$

$m = (Deltay)/(Deltax)$

$m=(y_2-y_1)/(x_2-x_1)$

$x_1=1$
$y_1=-3$
$x_2=8$
$y_2=-3$

$m = (-3-(-3))/(8-1)$

$m = (-3+3)/(8-1)$

$m=0/7$

The slope equals 0
This is a horizontal line through $y=-3$
