(If right ill mark brainliest) Please help! Thanks

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.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
