Find the residual values, and use the graphing calculator tool to make a residual plot

does the residual plot show that the line of best fit is appropriate for the data?

yes, the points are evenly distributed about the x-axis.
no, the points have no pattern.
no, the points are in a linear pattern.
yes, the points are in a curved pattern.

Solution-

We know that,

Residual value = Given value - Predicted value

The table for residual values is shown below,

Plotting a graph, by taking the residual values on ordinate and values of given x on abscissa, a random pattern is obtained where the points are evenly distributed about x-axis.

We know that,

If the points in a residual plot are randomly dispersed around the horizontal or x-axis, a linear regression model is appropriate for the data. Otherwise, a non-linear model is more appropriate.

As, in this case the points are distributed randomly around x-axis, so the residual plot show that the line of regression is best fit for the data set.
