3-62.

What is the equation of the line that has a $y$-intercept of $(0,−3)$ and passes through the point $(−9,−9)$? 3-62 HW eTool (Desmos).

Use the two points to find the rise and the run. Then divide the rise by the run. That will give you the slope.

Substitute the slope for $m$ in the equation below. Then substitute the $y$-coordinate of the $y$-intercept for $b$.

$y=mx+b$

$y=\frac{2}{3}x-3$
