First, multiply all fractions by 2.
3x-10/8x=52
Then multiply all sides by -10.
-30x + 8x = -520
-22x = -520
Divide both sides by -22.
x=23.6363

The axis of symmetry is found within the set of parenthesis with the x. If our h value of the vertex is -4, then the axis of symmetry is x = -4. D is that choice. Cannot graph it here, but your vertex is sitting at (-4, 4), it's an upside down parabola, and some other points on this graph are (-5, 0), (-3, 0), (-6, -12), (-2, -12). You could graph it using those points and the vertex without a problem, I'm sure.
