Find the equation of the regression line for the given data

Question:

Find the equation of the regression line for the given data

Then construct a scatter plot of the data and draw the regression line.​ (The pair of variables have a significant​ correlation.) Then use the regression equation to predict the value of y for each of the given​ x-values, if meaningful. The number of hours 6 students spent for a test and their scores on that test are shown below.

Here is the data set

Hours spent studying, x 0 1 3 3 5 6

Test score, y 40 44 50 49 61 72

then there is a section that says a) x= 2 hours b) x=3.5 hours c) x=13 hours d) x = 1.5 hours
