Help me with this math equation please (show all work)

answer: i think it is (1,-2)

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

i think it is c hope that
