blah blah blah
lots of words, but none of any use.
Since we cannot see the graph, including the line of best fit, there is no way to use that line to evaluate the function.
But it is clear that all you have to do is go along the Foot axis to where it says 8, and then go up to see where on the line is just above that point. Then go horizontally to the Arm axis to see how long the arm should be.
Looks like you need to learn how to read graphs...
The data on the graph show the foot lengths and forearm lengths for a group of people. The line of best fit for the data is shown. Use the equation of the line of best fit to predict the length of a person’s forearm if the length of their foot is 8 inches.
A graph is labeled as Foot Length versus Forearm Length. The horizontal axis is labeled as Length of Foot left parenthesis inches right parenthesis and the vertical axis is labeled as Length of Forearm left parenthesis inches right parenthesis. The values on the horizontal axis range from 0 to 15 in increments of 1 and the values on the vertical axis range from 0 to 15 in increments of 1. Several points are scattered throughout the graph and a line is shown which passes between these points and the equation of the line is labeled as y equals 1 decimal point 1 1 x minus 0 decimal point 8 3.
