Best ResponseYou've already chosen the best response.0if you are going to do it by hand, probably the best think to do if fine the intercepts

Best ResponseYou've already chosen the best response.0so for \[x3y=12\] find the x intercept by setting y = 0 get \[x=12\] so you know (12,0) is on the graph. for the y  intercept set x = 0 and get \[3y=12\implies y=4\] so you know (0,4) is on the graph. plot those two points, connect the dots

Best ResponseYou've already chosen the best response.0repeat the process for \[2xy=1\] or else rewrite as earthcitizen wrote as \[y=2x1\] and then replace x by some well chosen numbers and find a couple points
