Sofia is saving fan an iphone. she starts off with $50 that her parents gave her. she plans to deposit $30 per month from her paycheck. write an equation to represent how much money susan has saved. what does x represent and what does y represent draw a graph to represent how much money sofia has saved

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.
