Answer:
y = - x - 7
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 =
with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, - 7)
m = =
= -
The line crosses the y- axis at (0, - 7 ) ⇒ c = - 7
y = - x - 7 ← equation of line
