Answer:
y =
x + 4
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (0, 4)
m =
= 
Note the line crosses the y- axis at (0, 4) ⇒ c = 4
y =
x + 4 ← equation of line
