Question

Write the equation of a parabola with a vertex at (-5, 2) and a directrix y = -1

Answer 1

(x – h)^2 = 4p(y – k)

where h is the x in (-5,2)
and k is the y in (-5,2).
To find p:
|directrix-k| (absolute value)

Can you show me what the formula would look like with the numbers from your problem after I gave you this information?
