You can put this solution on YOUR website! Given the equation: x-y=4
Try the points, but remember that the first number is x, and the second number is y.
(3,1) : Does 3-1=4? NO!
(0,-4): Does 0-(-4) =4? YES!
(-4,0): Does -4-0 = 4? NO!
(-3,-7): Does -3-(-7)= 4? YES!
It looks like the correct answer is B.
