x has a value of 1. Use this value to find the value of y.

y has a value of 1.
x=1
y=1
Answer:
Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio--that is, when you divide any pair of the two values, you always get the same number k.
I wrote ones but I hope it’s right and helps
Is there a grid that came with the problem?
Answer: 2 197/1000
