Answer:
B
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 ) = (- 1, 1) and (x₂, y₂ ) = (1, - 3) ← 2 points on the line
m = = = - 2
Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 or
f(x) = - 2x - 1
