Answer
$y=-\frac{1}{3}x-11$
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= $−\frac{1}{3}$
y-intercept: $(0,−11)$
Thus, the slope-intercept form of the given line is:
$y=-\frac{1}{3}x+(-11)
\\y=-\frac{1}{3}x-11$
