Answer:

x = 2

y = 6

Step-by-step explanation:

x + y = 8

x + (3x) = 8

4x = 8

4x ÷ 4 = 8 ÷ 4

x = 2

-------------------------------

y = 3x

y = 3(2)

y = 6

----------------------------------

x + y = 8

(2) + (6) = 8

8 = 8

A function is when the x value has ITS OWN Y VALUE, so the x value can't have more than one y value.

Can't be B, because there are two x - values (6 and 6)

It can only be C, because each x-value has a different y-value
