The directrix is x=-2, which means the parabola opens horizontally instead of vertically. The equation is (y - k)²<span> = 4p (x - h), where the </span>focus<span> is (h + p, k) and the </span>directrix<span> is x = h - p in this case, h+p=2, k=0, and h-p=-2 solve for h and p: h=0, p=2 plug the numbers into the equation: (y-0)</span>²=4*2(x-0) simplify: y²=8x
