Write the equation of the line with $x$-intercept $(–4, 0)$ and $y$-intercept $(0, 9)$. Homework Help ✎

Use the slope-intercept form of a line ($y = mx + b$).

Substitute the $y$-coordinate of the $y$-intercept for $b$ in the equation.

Find the slope using any method you like, then substitute that value for $m$ to finish writing the equation.

$y=\frac{9}{4}+9$
