Fit a linear function to data when a scatter plot suggests a linear association.

Use a linear model to interpolate when a scatter plot shows an approximate straight-line pattern

Problem

A scatter plot shows an approximately linear pattern, and a model of \(y~=~4x~-~1\) is used. Estimate the output when the input is \(5\). The observed input values on the scatter plot range from \(2~\text{to}~9\), so this is interpolation.
