You can put this solution on YOUR website!
Required a substitution and then some detailed algebra steps - that was all. I solved this a few minutes ago in your other identical request. None of your choices were what I found.

Your system is a circle and a line.
x%5E2%2By%5E2=1 and -2y=-x+4 or y=x%2F2-2.

graph%28-3%2C3%2C-3%2C3%2Csqrt%281-x%5E2%29%2C-sqrt%281-x%5E2%29%2Cx%2F2-2%29
(While I was rechecking this posting, the graph would not display, even though the code and rendering tags seem to all be correct)
