If you have two points and want to find the equation for the line, you use the two-point form equation.

The formula is $y - y_1 = \frac{y_2 - y_1}{x_2 - x_1}(x - x_1)$

Well, make the x-intercept the point (x_1, y_1)

and the y-intercept the point (x_2, y_2)

Plug in the values.

$y - 0 = \frac{4 - 0}{0 - (-2)}(x - (-2))$

Simplify.

$y - 0 = \frac{4 - 0}{0 - (-2)}(x - (-2))$
$y - 0 = \frac{4}{2}(x - (-2))$
y - 0 = 2(x - (-2))
