Best ResponseYou've already chosen the best response.0In an ordered pair (1,3) the first number is the x and the second is the y (x,y) so you put 1 in for x and 3 in for y 2(3) + (1) = 5 6 + (1) = 5 5 = 5 so that point (1,3) is on the line 2x + y = 5 now try the next point and I will check you out.

Best ResponseYou've already chosen the best response.0OK.. the point is (7,1) so x = 7 and y = 1 your equation is 2y + x = 5 make sure you put in x = 7 and y = 1

Best ResponseYou've already chosen the best response.02(1) + 7 = 5 2 + 7 = 5 5 = 5 so (7,1) is also on that line... it is a solution.

Best ResponseYou've already chosen the best response.0yes... it is a coordinate.. but you put the x value of 7 into the y variable and you put the y value of 1 into the x variable. that is the mistake you made.
