Question

Determine if John's wages are proportional to time. If they are, determine the unit rate y/x. If not, explain why not.

Answer 1

Answer:

- Student cannot determine proportionality because there is no y-intercept.

- Table and graph do not match

  (Student does not realize they are based on two different people)

- Student computes x/y and not y/x (Ex. 3/27 or 2/18)

Step-by-step explanation:

-May not be able to determine Unit rate because (1, r) does not exist on the table.

-May answer “18” because it is the first point on the table.

-Unable to determine relationship between x and y values
