Answer:
C.
Step-by-step explanation:
C. (-7, 2), (-1, 3), (4,7), (7,2)
The values of x are not repeating, so this is a function, because for every x has only one corresponding value of y.
1/2
there are two numbers 3 and 6 so 2/6 is 1/3
x = a number
4x - 63 = x
Subtract 4x from both sides.
-63 = -3x
Divide both sides by -3
21 = x
i think it is 31 maybe
