The slope was found to be b, = 6.715 and will be used to find the intercept, bo. The formula for the slope follows. bo = y – b,x Substitute the computed values b, = 6.715, y = 228.9, and x = 31.6 into the formula to find the y intercept bo, rounding the result to three decimal places. bo = y - b,x = 228.9 – 6.715( 31.6 = 16.706 Therefore, the estimated linear regression equation is as follows where the slope and y-intercept are rounded to three decimal places. ŷ = 16.706 + 6.715x x
