Answer:

y - intercept = - 12

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 = [tex]\frac{1}{4}[/tex] , thus

y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

To find c substitute (12, - 9) into the partial equation

- 9 = 3 + c ⇒ c = - 9 - 3 = - 12 ← y- intercept
