From the Figure :
Point A is (-3 , -3)
Point B is (6 , 6)
We know that, The Mid Point of Two Points (x₁ , y₁) and (x₂ , y₂) is given by :

Answer:
The equation of the line would be y = -2x + 7
Step-by-step explanation:
In order to solve this, use the point and the slope in point-slope form. Then solve for y.
y - y1 = m(x - x1)
y - 5 = -2(x - 1)
y - 5 = -2x + 2
y = -2x + 7
