(8r^2-7r-9) +(-r^2+r)=(8r 2 −7r−9)+(−r 2 +r)

r = 0 , 2

Step-by-step explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

was I supposed to solve for R? If so here you go.

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.
