Question

the scatterplot shows the relationship between two variables, x and y. a line of best fit for the data is also shown. for how many of the 9 data points does the line of best fit predict a y - value that is less than the actual y - value?

Explanation:

Step1: Inspect each data - point

For each of the 9 data - points on the scatter - plot, compare the y - value on the line of best fit with the actual y - value of the data - point.

Step2: Count the number of points

Count the number of data - points for which the y - value on the line of best fit is less than the actual y - value.
By observing the scatter - plot, we can see that for 4 of the 9 data - points, the line of best fit predicts a y - value that is less than the actual y - value.
