Hello! I have the following equation to graph.

4x^2+y^2+8x-y+7=0.

I know that this is a circle but I only know how to graph it when there are simply a y^2 and x^2. The other variables are confusing me..what should I do? Thank you!

i also just figured out that the radius is 1 and the center (1,2) but what will the "4" do to the circle?
