The table shows a direct variation.

What is the constant of variation?

x y

2 4.8

4.5 10.8

6 14.4

For any direct variation: x=ky so k=x/y

k=4.8/2=2.4

k=10.8/4.5=2.4

k=14.4/6=2.4

Since k is a constant, you get the same value when you use any set of x and y values from the table. I just wanted to show you that.

The constant of variation (k) = 2.4
