Answer: 0.2
====================================================
Step-by-step explanation:
For each row, divide y over x to find r
This is because y = rx solves to r = y/x
- Row one: r = y/x = (1.6)/8 = 0.2
- Row two: r = y/x = 3/15 = 0.2
- Row three: r = y/x = (4.4)/22 = 0.2
We get r = 0.2 each time to confirm that x and y are directly proportional.
The equation goes from y = rx to y = 0.2x
Note: 0.2 converts to the fraction 1/5
