Sea level is considered to be 0 feet. a probe released at sea level dropped at a constant rate for 3.25 minutes, reaching an elevation of −35.75 feet relative to sea level.
what was the probe's elevation relative to sea level after the first minute?

step-by-step explanation:

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.
