On your own graph paper, draw axes, decide on a scale, and plot points to represent the data in the table at right. Does this data appear to be proportional? Explain why or why not.

Quantity X Quantity Y
2 6.3
6 18.9
9 28.35
5 15.75
1 3.15

Answer 1

3.15

Explanation:

This graph is proportional. divide the y by x (k=y/x) (constant of proportionality. 6.3/3=3.15 18.9/6=3.15 28.35/9=3.15 15.75/6=3.15 3.15/1=3.15
