Question

What is the equation of the parabola with a focus at (0, -5) and directrix y = 5?
PLEASE HELP FAST

Answer 1

make a sketch

Answer 2

If you have two points the focus \((x_1, y_1)\) and directrix \((x_2, y_2)\), insert both points in to the distance formula:

\((x - x_1)^2 + (y - y_1)^2 = (x - x_2)^2 + (y - y_2)^2\)

Then simplify.

In this case, the focus is (0,5). The directrix is (x, 5)

Answer 3

Sorry, the focus is (0, -5)
