Jamie is walking her neighbors’ dog while they are away. She is keeping track of the total number of blocks she walks over time.
A 2-column table with 3 rows. Column 1 is labeled Minutes with entries 6, 14, 20. Column 2 is labeled Blocks with entries 3, 7, 10.
Does the table represent a proportional relationship?
A Yes, because both columns are written in ascending order.
B Yes, because the values in the second column are less than the values in the first column.
C Yes, because the ratios are equivalent between each pair of values.
D No, because the values in the table do not increase by the same amount in each row.
