Question

Magan decides to research the relationship between the length in inches and the

Answer 1

Based on the line of best fit, the length of this catfish can be predicted to be 38 inches.

Given the following data:

• Weight of catfish, x = 40 pounds.

What is a line of best fit?

A line of best fit is also referred to as a trend line and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any correlation between a data.

From the graph of the data, we have the following linear equation:

$y=\frac{1}{2} x+18$

Substituting the value of x, we have:

$y=(\frac{1}{2} \times 40 )+18\\\\y=20+18$

y = 38 inches.
