Answer:
y = 5x - 18
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 = 5 , thus
y = 5x + c ← is the partial equation
To find c, substitute (3, - 3) into the partial equation
- 3 = 15 + c ⇒ c = - 3 - 15 = - 18
y = 5x - 18 ← equation of line
