Question

1. (standard 7.pr.4) determine if the relationship shown in the table below is proportional. explain your answer by checking the ratio ($\frac{y}{x}$) for each pair of values.

Explanation:

To determine if a relationship is proportional, we check if the ratio \(\frac{y}{x}\) (assuming \(y\) and \(x\) are the two variables) is constant for all pairs of values. However, since the table is not provided, we can't calculate the ratios. But the general method is:

1. For each row in the table (each pair of \(x\) and \(y\) values), calculate the ratio \(\frac{y}{x}\) (or \(\frac{x}{y}\) depending on which variable is dependent/independent).
2. If all these ratios are equal, then the relationship is proportional. If the ratios are not equal, then the relationship is not proportional.

For example, if the table had values like:

\(x\)	\(y\)
3	6
4	8

We would calculate \(\frac{4}{2} = 2\), \(\frac{6}{3} = 2\), \(\frac{8}{4} = 2\). Since all ratios are equal (2), the relationship is proportional.

If the table had values like:

\(x\)	\(y\)
3	7
4	10

We would calculate \(\frac{4}{2} = 2\), \(\frac{7}{3} \approx 2.33\), \(\frac{10}{4} = 2.5\). Since the ratios are not equal, the relationship is not proportional.

Since the table is missing from your question, please provide the table with the \(x\) and \(y\) (or other variable) values so that we can check the ratios and determine if the relationship is proportional.
