Ok so, Find the coordinates of the points of intersection.
X-3=0
X^2 + Y^2 = 36
No idea what to do but they tell me the answer is
3, 3 root 3. 0.0?
Please help.

The first equation is a vertical line at x = 3.
The second equation is a circle centered at the origin with a radius of 6.

x-3=0 
x=3

Put it in 2nd equation:
$$3^2+y^2=36$$
$$y^2=27$$
$$y=\pm \sqrt{27}=\pm3\sqrt3$$
