Answer:
y- intercept = - 11
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 )
here m = - 3 , then
y = - 3x + c ← is the partial equation
to find c substitute (- 5, 4 ) into the partial equation
4 = - 3(- 5) + c = 15 + c ⇒ c = 4 - 15 = - 11
the y- intercept = - 11
