Hi dazygrl02,

If you sketch the graph...plot the vertex and focus...you will see that the parabola opens to the left.

The standard form for this parabola is , where

Now, the vertex is at(h, k)which makesh = 8, andk = 6.

The focus is defined as

Since your focus is at(2, 6),that would make

Solve fora.

Now you havea,h, andk.

Substitute into , and there you have it.
