Answer:

C

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 )

Given

y + 3 = 5(x - 3) ← distribute right side

y + 3 = 5x - 15 ( subtract 3 from both sides )

y = 5x - 18 ← in slope- intercept form

with y- intercept c = - 18 ⇒ (0, - 18 ) → C
