The graph represents the relationship between the number of rocks a child collects, r, over a number of weeks, w.
Which function can be used to determine the number of rocks, r,
a child will collect after w weeks?
O r= 15w + 5
or=tw +15
op=
- Tow+5
O r = 5W + 15

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.
