You can put this solution on YOUR website! Which of the ordered pairs (3,1), (0,-4), (-4,0), (-3,-7) are solutions for the equation x-y=4
The question is asking which set of points will make this equation true. That is, when you plug in the points which of these pairs will equal 4.
To solve this problem, you will need to plug-in each pair of points separtately until you find the pair that gives you the correct answer.
The first number in each set of points is the "x" value; the second number in each set of points is the "y" value: So, plugging in the first set of points you get:
x-y=4
3-1=2
This is not correct becasue the answer is 2; not 4.
Try plugging in the last set:
x-y=4
-3 - (-7)= -3+7 = 4
This is one of the answers. I think there may be more than one answer, so try plugging in the other two points to make sure.
