First step is to solve the given equation for y. So, subtract x from each sides to isolate y. Therefore,
x + y - x = 2 - x
y = 2 -x.
Next step is to plug in the values of x = -4, 0 and 4 to get the corresponding values of y's so that we can get the correct order pair.
Let's plug in x = -4 now.
So, y = 2 - ( - 4) = 2 + 4 = 6
So, the first order pair is (- 4, 6).
For x = 0, y = 2 - 0 = 2
Second order pair is (0, 2).
For x = 4, y = 2 - 4 = -2.
Third order pair is (4, -2)
So, third list of order pairs (-4, 6), (0, 2), (4, -2) represent the solutions.
Hope this helps you!
