The value of y can be determined by using the expression 3.25x. Which table represents the relationship between the values x and y?

The answer is a (or the box on the top left). because y=3.25x, all you have to do is plug in x with the numbers from the tables, to find out what y is. (you could also plug y in to find out x, but i find it easier to plug x in to find out y).
work shown:
3.25(0)=0
x y
3.25(2)=6.5
x y
3.25(5)=16.25
x y
3.25(6)=19.5
x y
