Question

Which table as a consistent of proportionately between Y and X of two?

1. X- Y-
2 5
6 15
12 30

2. X- Y-
3 6
5 10
18 36

3. X- Y-
6 24
10 40
14 56

Answer 1

The table that has a consistent proportionality between Y and X of 2 is choice 2.

Explanation:

Because the proportionality between X and Y is 2, that means for each x value, the corresponding y value will be twice as big. The only option that meets this requirement is choice 2, so that is the correct answer.
