The slope equals $3/2$

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

Slope is identified by the letter $m$

$m = (Deltay)/(Deltax)$

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

$(2,-7)$ and $(4,-4)$

$x_1=2$
$y_1=-7$
$x_2=4$
$y_2=-4$

$m = ((-4)-(-7))/(4-2)$

$m = (-4+7)/(4-2)$

$m = (3)/(2)$

The slope equals $3/2$
