ANSWER

p = - 2

Step-by-step explanation

The given equation is

$x = - (1)/(8){y}^(2)$

Multiply both sides by -8

$\implies \: {y}^(2) = - 8x$

We now compare this to the general equation of the parabola:

${y}^(2) = 4px$

This implies that,

4p = - 8

Divide both sides by 4.

p = ( - 8)/(4)

p = - 2
