For each ordered pair, substitute the values of x and y into the equation to see if the statement is true. If the statement is true, then the ordered pair is a solution.
(3,1): 3-1=4, which becomes 2=4, which is FALSE
(0,-4): 0-(-4)=4, which becomes 4=4, which is TRUE
(-4,0): -4-0=4, which becomes -4=4, which is FALSE
(-3,-7): -3+7=4, which becomes 4=4, which is TRUE
So, the ordered pairs that are solutions are (0,-4) and (-3,-7), or answer (C).
