Can someone tell me if this is right

What is the range of the relation in the table below? x y –2 0 –1 2 0 4 1 2 2 0

What term makes it inconsistent y=2x - 4

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
