Which system of equations is represented by the graph?

Answer:CStep-by-step explanation:y=x is a line that has slope 1 meaning it go ups (increases) from left to right.So that puts us at choice A or C.Both A or C differ by the numerator for the other function.We can find the x-intercept for A and C by setting the numerator equal to 0 and solving for x.Let's do that:A:  -x-10=0                           C.  -x+10=0      -x=10                                    -x=-10       x=-10                                    x=10A says x-intercept -10C says x-intercept 10Your graph intercepts the x-axis at 10 so the answer is C.
