Question 206774
alright... so actually dont stress out.. its a simple question that you may be overthinking. if you are already given a replacement set, then plug in each set to see which one will work.. watch this dude.
 
y=3x-1
5=6-1
yes! thats the answer ya see.??? cuz whenever you see (x,y) thats how you should look at it... like the 2 would be substituded as x and the five as y.. 
hope you get it man..
