Answer:
y = 3x + 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 ) = (0, 4) and (x₂, y₂ ) = (- 4, - 8)
m = [tex]\frac{-8-4}{-4-0}[/tex] = [tex]\frac{-12}{-4}[/tex] = 3
Note the line passes through the y- axis at (0, 4) ⇒ c = 4
y = 3x + 4 ← equation of line
