A line has intercepts $\left(4,0\right)$ and $\left(0,-3\right)$ . Find the equation of the line.

Hint 1:

Graph the two points on your paper in order to make a slope triangle to find the slope of the line.

Hint 2:

Use the given $y$ -intercept $\left(0,-3\right)$ to substitute for $b$ in the $y = mx + b$ form of a line. Therefore; $b=-3$ .

Hint 3:

Substitute $m$ and $b$ back into their positions in the equation.

Answer:

$y=\frac{3}{4}x-3$
