Question

what does a linear equation allow you to do with data points on a scatter plot?
a. calculate the median
b. determine the mode
c. find the range of the data set
d. make predictions about future data points

Explanation:

A linear equation (like a regression line in statistics) models the relationship between variables. Once the line is established (using the scatter - plot data points), it can be used to predict values for new (future) data points by plugging in the relevant input values into the equation. The median (a measure of central tendency) is calculated by ordering data values. The mode is the most frequently occurring value. The range is the difference between the maximum and minimum values in a data set. None of these (median, mode, range) are directly related to what a linear equation does with scatter - plot data points for prediction purposes.

Answer:

D. Make predictions about future data points
