Hlp i need a quick answer w/explanation

The answer is: -2.

Step-by-step explanation:

Note when x = -2 that the line passes through the point (-2, -2) so when x = -2 then y also = -2.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
