Answer: A
Step-by-step explanation: A function means that your x can only have one y but your y can have multiple x's.
D)y=1/4x represents a proportional relationship
We are given
First equation:

we can use formula

slope is m=1
y-intercept is b=-1
Second equation:

we can use formula

slope is m=-2
y-intercept is b=5
Graph:
We can see that
both curves intersect at (2,1)
so, solution is x=2 and y=1.................Answer
From the looks of it, I believe it is either 120, 125, or 126. If you have options, let me know so I can take a closer look.
