The answer is correct but the method is "Using Linear combination", not using graphs

anonymous · Answer

okay then the formula is 
y=mx+c

loser66 · Answer

Linear combination method is the method you +/ - two given equations together. In this case, you take the first one - the second one to get x =0, then plug it into one of the given equations to get y. 
Fortunately, only 1 option has x =0, hence you save your time.
