Answer:
y = 3x - 28
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
To find c substitute (8, - 4) into the partial equation
- 4 = 24 + c ⇒ c = - 4 - 24 = - 28
y = 3x - 28 ← equation of line
