(b) Find a linear equation that relates Loraine's weekly test score y to the amount of time she studies per day X. Express numbers in exact simplest form. (Hint: Pick two ordered pairs from the observed data and find an equation of the line through the points.) The linear equation in slope-intercept form (y= mx+b) is

Loraine is enrolled in an algebra dlass that meets 5 days per week. Her instructor gives a test every Friday. Loraine has a study plan and keeps a portfolio with
notes, homework, test correctións, and vocabulary. She also records the amount of time per day that she studies and does homework. The following data
represent the amount of time she studied per day and her weekly test grades.
