Using previously given equation, the estimate of the GPA of a student who studies for 15 hours a week is; 3.1
<h3>How to predict an equation?</h3>
The equation here is probably a "best fit" equation based upon given data which is GPA versus the number of hours of study per week.
Now, the equation of best fit is given as;
y = 0.149x + 0.89
Thus, if the number of study hours of interest is 15, then the GPA is;
GPA = 0.149(15) + 0.89
GPA = 3.1
