Consider the quadratic function that has x-intercepts of -1 and -7 and passes through the point (-2, -20). What is the value of a in the factored form of this function? 0 1 02 O 3 O 4​

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.
