Part 2 of 5 The data points appear to follow a linear trend. Part: 2 / 5 Part 3 of 5 (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 O=0
