Find a function to represent the set of all points equidistant from the point(-2,3) and the line y=7.

That line is a parabola. (-2,3) is the focus. y=7 is called the directrix. You probably have some text or lecture notes that tell you how to relate those facts to the equation you need. We will be glad to critique your work.

I have suggested you review how to relate the equation of a parabola to the position of the focus and the directrix. You must have a section in your text that discusses this. If there is none, I suggest you review
