The numbers in the ordered pairs correspond to the x and y variable respectively. Solve for both x and y and simply plug which ever coordinate you have into the right equation to get what you need: x = ( 12 - 4y )/3 y = ( 12 - 3x )/4 So: for (0,), use the 'y' equation: y = ( 12 - 3(0) )/4 = 3 Answer: (0, 3) for (,3/4), use the 'x' equation: x = ( 12 - 4(3/4) )/3 = 3 Answer: (3, 3/4) The rest: (8/3,) is: y = ( 12 - 3(8/3) )/4 = 1 Answer: (8/3, 1) (,0) is: x = ( 12 - 4(0) )/3 = 4 Answer: (4,0)

When y = 0 then x = 4
When y = 3/4 then x = 3
The third one is the same as the first one
When y = 8/3 then x = 4/9

3x + 4y =12 (4,0), (3, 3/4), (4,0),(4/9,8/3)
3x + 4(0)= 12
3x = 12
x = 12/4
x = 4
3x + 4(3/4) = 12
3x = 12 - 3
3x = 9
x = 9/3
x = 3
3x + 4(8/3) = 12
3x = 12 - 32/3
3x = 4/3
x = 4/9
