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 in the image.  Find the regression equation

y^=[ ]x +([ ])

​(Round the slope to three decimal places as needed. Round the​ y-intercept to two decimal places as​ needed.)
