How to tell if a table is proportional?
Understand the Problem
The question is asking for guidance on determining if a table of values shows proportional relationships, which typically involves analyzing the ratios or changes between corresponding values in the table.
Answer
Calculate the ratio of each pair of values; if all are equal, the table is proportional.
You can tell if a table is proportional by calculating the ratio of each pair of values. If all ratios are the same, then the table shows a proportional relationship.
Answer for screen readers
You can tell if a table is proportional by calculating the ratio of each pair of values. If all ratios are the same, then the table shows a proportional relationship.
More Information
A proportional relationship in a table is consistent if the ratios of corresponding values (y divided by x) are constant.
Tips
Common mistakes include not reducing fractions to their simplest form and ignoring minor differences in the ratios.
