Answer
$y=-\dfrac{2}{3}(x-5)$
Work Step by Step
Using $y-y_1=m(x-x_1)$ or the Point-Slope form where $m$ is the slope and $(x_1,y_1)$ is a point on the line, then the equation of the line with the given slope equal to $
-\dfrac{2}{3}
$ and with the given point $\left(
5,0
\right)$ is
\begin{array}{l}
y=-\dfrac{2}{3}(x-5)
.\end{array}
