# Math Help - straight line

1. ## straight line

Explain how a straight line graph can be drawn from the equation 16p^2(x)=(y-q)^2 where p and q are constants.State the gradient and the y-intercept of the straight line graph in terms of p and q.

2. ## Tricky

$16x*p^2 = (y-q)^2$

Take the square root of both sides:

$4p \sqrt{x} = y-q$

or

$y = 4p \sqrt{x} +q$
