Well i do hate study island

y=2x+5 automatically u can see the y intercept is 5 so it has to be this one. But also u can see the slope going up by 2

Step-by-step explanation:

also I hate study Island too I rmbr using it in like the 5th grade. Bet its changed alot now.

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.

step-by-step explanation:

the true ones are a b and d
