Consider the parabola with a focus at the point (0,7) and directrix y = 1. Which two equations can be used to correctly relate the distances from the
focus and the directrix to any point (x, y) on the parabola?
A. a = y - 1; a = V(X +
+0)2 + (y + 7)2
O B. a = 1 = y; 2 = V(x+0)2 + (y - 7y?
O C. a= y-t a = (x+0)2 + (y - 7)?
O D. a = 1- y, a = (x+0)2 + (y + 7)?
