A co-worker is working on a top-secret project was able to figure out how to fit a linear regression line to their data; however, they do not know how to interpret that linear regression equation or what the equation can tell them about the relationship between the two undisclosed variables (let's simply call them X and Y). They were also given a task to give their best estimate for the value of y, when x is equal to 140.
Since they are not sure what to do next, they come to you for help knowing that you have taken a basic statistics course. Help your co-worker interpret the linear relationship between x and y by answering the following problems, given their scatter plot with plotted linear regression line, and the equation of their linear regression line, displayed here.
Given the linear regression equation created by your co-worker, what would be the best estimate for the value of y, in the case where x = 140?
