Answer:
Proportional
y is 0.4 times x
or
y is 2/5 times x
Both numbers are the same, I don't know which form the computer expects you to enter
Explanation:
x and y are proportional since there is a linear relationship between y and x.
Let's verify this
When x = 5, y = 2. So y/x = 2/5 = 0.4
So y = 0.4x
When x = 10, y = 4
So y/x = 4/10 = 2/5 = 0.4
Again y = 0.4x
So the answer is 0.4, same as 2/5
