# Find the ve

Given equation of the parabola is y2 = 8x + 8y

y2 - 8y = 8x

y2 - 8y + 16 = 8x + 16

(y - 4)2 = 8(x + 2)

Comparing with the standard form of parabola (y - a)2 = 4b(x - c) we get,

4b = 8

b = 2

The vertex is (c, a) = (- 2, 4)

The focus is (b + c, a) =

The equation of the axis is y - a = 0 i.e, y - 4 = 0

The equation of the directrix is x - c = - b

Directrix is x - (-2) = -2

Directrix is x = -2 -2

Directrix is x = -4

Length of latus rectum is 4b = 8.
