Answer
$y=-\frac{2}{3}x-10$
Work Step by Step
RECALL:
The slope-intercept form of a line's equation is $y=mx+b$ where $m$ = slope and $(0, b)$ is the line's y-intercept.
The given equation has
slope = $-\frac{2}{3}$
y-intercept: $(0, -10)$
Thus, the equation of the line is:
$y=-\frac{2}{3}x+(-10)
\\y=-\frac{2}{3}x-10$
