The distance is $15$ units.

#### Explanation:

This is the formula of the distance between two points.

$d = \sqrt{{\left({x}_{b} - {x}_{a}\right)}^{2} + {\left({y}_{b} - {y}_{a}\right)}^{2}}$

where $a \left({x}_{a} , {y}_{a}\right)$ and $b \left({x}_{b} , {y}_{b}\right)$ the points in question.

$d = \sqrt{{\left(- 8 - 7\right)}^{2} + {\left(4 - 4\right)}^{2}} = \sqrt{{\left(- 15\right)}^{2}} = 15$.
