Answer:
C. (–3, –7)
Explanation:
We can check each ordered pair by substituting the values of x and y into the equation y = x - 4 and see if the equation is true.
A. (-3, 7)
y = x - 4
7 = -3 - 4
7 = -7
This is not true, so (-3, 7) is not a solution.
B. (3, -7)
y = x - 4
-7 = 3 - 4
-7 = -1
This is not true, so (3, -7) is not a solution.
C. (-3, -7)
y = x - 4
-7 = -3 - 4
-7 = -7
This is true, so (-3, -7) is a solution.
D. (3, 7)
y = x - 4
7 = 3 - 4
7 = -1
This is not true, so (3, 7) is not a solution.
Therefore, the only ordered pair that is a solution of y = x - 4 is (–3, –7).
