Answer :
(4 + (-4))/2 = 0/2 = 0
The midpoint is x=0, which is the equation of the axis of symmetry for this parabola.
The midpoint is x=0, which is the equation of the axis of symmetry for this parabola.
SInce both lines run through (4,-4) they meet up at 0 on the Y axis which means the answer to the question is (0,0)
