The purpose of the best-fit line on an experimental scatterplot is to:. a. The best-fit line allows us to predict behavior between measured data using its slope.
b. Ignore data points that don't fit the line.
c. Determine individual slopes between each set of data points

a. The best-fit line allows us to predict behavior between measured data using its slope.

Explanation:

A line of best fit is drawn through a scatter-plot to determine the direction of an relation between two quantities.

The line of best fit can be used to make prediction for the dependent variables.

Hence, the purpose of the best-fit line on an experimental scatter-plot is to predict behavior between measured data using its slope.

Hence, the correct option is "a."
