The vertex form of the equation of a parabola that opens to the right with vertex (h,k) is
In that formula, p is the directed distance from the vertex to the focus; since in this problem the parabola opens to the right, p is positive.
Then, since the vertex is (0,0) and the directed distance p from the vertex to the focus is 7, the equation is
