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
