•The following system of functions are shown on the graph: y=-x+6 y=x+2 •Johnny answered that the solution to the system is (4,2) •Erica answered that the solution to the system is (2,6) •Which student is correct ? •Why are they correct?
knowing that the system are y=-x+6 and y=x+2, then: x+2=-x+6; x+x=6-2; 2x=4; x=2, and replacing x in y we have: y=-2+6=4 and y=2+2=4, finally tha solution to sistem is (2,4)
