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, thus
y = - 3x + c ← is the partial equation of the line
To find c substitute (- 5, 4) into the partial equation
4 = 15 + c ⇒ c = 4 - 15 = - 11 ← y- intercept
