Answer:
y = 3x + 17
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 , then
y = 3x + c ← is the partial equation
to find c substitute (- 5, 2) , that is x = - 5, y = 2 into the partial equation
2 = - 15 + c ⇒ c = 2 + 15 = 17
y = 3x + 17 ← equation of line
