Question

the graph below shows a set of data and the line of best fit. complete the sentence to make a true statement. if the point (9, 9) were removed from the data set, the slope of the line of best fit would and the y - intercept would

Explanation:

Step1: Analyze out - lier effect

The point (9, 9) is an out - lier above the line of best fit. Removing it will make the line fit the remaining data better.

Step2: Consider slope and intercept

The out - lier pulls the line up on the right - hand side. Removing it will make the slope less negative and the y - intercept decrease.

Answer:

The slope of the line of best fit would increase and the y - intercept would decrease.
