Question

is the relationship represented by the table proportional or not? show how do you know on the sketchpad (Table is shown on the sketchpad.)
if it is proportional, what is the constant of proportionality (COP)?

Answer 1

Answer:

No, the table is not proportional. I know this because when you divide x by y the answer is not the same.

y/x = Unit rate or constant rate

Work : (The numbers that are bold are the quotient of y/x)

85 = 17       79 = 7.9      73 = 3.65    67 = 1.67

5                10               20               40
