Name Section 4.2 Show all your work An instructor used 20 students to study the relationship between number of absences (x) and final grade (y) in a class. Use: = 3.1, sx = 1.75, y = 83.4, sy = 7.03 x Sx and r=-0.861 to find the linear regression equation (linear correlation equation) y = a + bx for this data. Round your final answer to two decimal places. la.) Linear Regression Equation: y = a + bx 1 b.) slope of the line: b = r. Sy Sx y-intercept of the line: a =ỹ - b*
