WV bisects XWY. The measure of angle XWV is (x+3), and the measure of angle VWY is (3x-91). Solve for x.

Then the vertex is at (h, k) = (2, - 3) and the value of p is - 3. Since y is squared and p is negative, then this is a sideways parabola that opens to the left. This puts the focus 3 units to the left of the vertex.

vertex: (2, - 3); focus: (-1, - 3)
