## anonymous one year ago Help please?? What are the foci of the following graph?

1. anonymous

2. anonymous

im not sure about this and i might not make any sense but i think the number 2? sorry i hate math :/

$center=(\frac{+6-4}{2},2)=(1,2)\\2a=6-(-4)=10\\a=5\\so\\\frac{(x-x_{center})^2}{a^2}-\frac{(y-y_{center})^2}{b^2}=1\\\frac{(x-1)^2}{5^2}-\frac{(y-2)^2}{b^2}=1$

now note that graph meet (8,0) or ((-6,0) so you can find b then $c^2=a^2+b^2$
