To determine if a table shows a proportional relationship, you would typically check if the ratio of the two quantities involved is constant across all pairs of values in the table. The constant of proportionality (if it exists) is the value of that ratio.
However, since you did not provide the actual values in the table, I cannot directly assess whether it shows a proportional relationship or identify the constant of proportionality.
If you provide the specific values from the table, I can help you determine if a proportional relationship exists and what the constant of proportionality is if it does.
