The table below lists the number of hours each student in a small class spent studying for a test, and that student\'s test score. The line of best fit for the data is y = 5x + 60. According to the meaning of the slope of the equation, for every additional 1 hour spent studying, by how many points does a student\'s test score increase?

Solution

y = 5x + 60

According to the meaning of slope of the equaton, for every additional 1 hour spent studying ,5 points a students test score increases.

Note: Slope of a least-squares regression line

The amount by which the response variable increases or decreases, on average, when the explanatory variable increases by one.
