Answer:
x y
0.75 6
1.5 12
3 24
Explanation:
Proportional relationship between x and y is often written as y = kx.
In the table,
x = 0.75 and y = 6
x = 1.5 and y is unknown.
Since
then

When multiplying 12 by 2, you get 24 and when multiplying 1.5 by 2, you get 3, so the last row is x = 3 and y = 24.
