Question 1117018: I am not sure of how to set up this equation and solve it:
Write an equation for a parabola with a focus of (2,2) and directrix of y =4
Options:
y = 1/4 (x-2) ^2 +3
y = - 1/4 (x-2) ^2 + 3
y = -1/2 (x+2)^2 +3
y =1/2 (x+2)^2 +3

You could use the Distance Formula definition for Parabola and start with this:

Points (x,y) will fit

Work through the algebra steps to put into the form you want and then make the proper choice.
