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?
a 0
b 3
c 6
d 9

Explanation:

Step1: Understand the scatter - plot and line of best fit concept

The line of best fit is a straight line that best represents the data on a scatter - plot. If a data point is above the line of best fit, the predicted \(y\) - value (from the line) is less than the actual \(y\) - value.

Step2: Count the number of data points above the line

By visually inspecting the scatter - plot, we count the number of data points that lie above the line of best fit.
