It’s A). x=20 y=128.
do you need the work?

A linear function has 1 as the highest power of the variable.
A. f(x) = 2 - 7x
here, the highest power of the variable x is 1.
Hence it is a LINEAR function.
___________
B. f(x) = 2 + x + x^2
here, the highest power of the variable x is 2.
Hence it is NOT a linear function.
_______________

here, the highest power of the variable x is 1/2.
Hence it is NOT a linear function.
________________
Step-by-step explanation:
If y was directly proportional to x, the graph of y against x would pass through the origin (O).
Since the graph above does not show this, y is not directly proportional to x.
Hey sorry I can’t see the question I see the graph though
Answer:
(4,-8)
Step-by-step explanation:
Where is the point on the opposite side of the y-axis?
The answer would be (4, -8)
