Answer
$y=-\frac{5}{3}x$
slope = $-\frac{5}{3}$
y-intercept = 0
Work Step by Step
RECALL:
The slope-intercept form of a line's equation is given as $y=mx+b$ where m = slope and b = y-intercept.
Divide $-3$ on both sides of the equation to obtain:
$y=\frac{5x}{-3}
\\y=-\frac{5}{3}x$
The line has a slope of $-\frac{5}{3}$ and a y-intercept of $0$.
