7-106.

Find the equation of the line with $x$-intercept $(–4, 0)$ and y-intercept $\left(0, 9\right)$.

$y = mx + b$

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.

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