Answer:
y = 3x - 31
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
To find c substitute (9, - 4) into the partial equation
- 4 = 27 + c ⇒ c = - 4 - 27 = - 31
y = 3x - 31 ← equation in slope- intercept form
