A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](/tpl/images/2464/7987/287b9.png)
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 4) ← 2 points on the line
m =
=
=
= 2
The line crosses the y- axis at (0, 4 ) ⇒ c = 4
y = 2x + 4 → A
