Question

lincoln decides to research the relationship between the length in inches and the weight of a certain species of catfish. he measures the length and weight of a number of specimens he catches then throws back into the water. after plotting all his data, he draws a line of best fit. what is the meaning of the $x$-value on the line when $y = 29$? answer the expected weight of a catfish that is 29 inches long. lincoln caught a catfish 29 inches long. lincoln caught a catfish that weighed 29 pounds. the expected length of a catfish that weighs 29 pounds.

Explanation:

In a scatter - plot with a line of best fit, the \(x\) - axis represents the length of the catfish (in inches) and the \(y\) - axis represents the weight of the catfish (in pounds). When we are looking for the \(x\) - value on the line of best fit for a given \(y = 29\) (where \(y\) is weight), we are using the line of best fit to predict the \(x\) (length) value corresponding to that \(y\) (weight) value.

Answer:

The expected length of a catfish that weighs 29 pounds.
