The graph below shows a set of data and the line of best fit.

Question

Complete the sentence to make a true statement.
If the point (10,2) were removed from the data set, the slope of the line of best fit would_____
and the y-intercept would ______
_____= decrease, increase, or stay the same

Answer 1

If the point (10,2) were removed from the data set, the slope of the line of best fit would increase and the y-intercept would stay the same.

This conclusion can vary based on the specific characteristics of the data, but generally, if the removed point is below the line of best fit, it can cause the slope to increase. The y-intercept typically remains unchanged unless the overall positioning of the data points shifts significantly, which is generally less likely. Always check the specific graph for accuracy.
