Step 1: Determine the equation of the regression line. The general equation for the regression line of y on x is y = ax + b. From the problem statement and the partial solution, we are given the gradient a = (3)/(5) and we have calculated the y-intercept b = -2. Substitute these values into the equation: y = (3)/(5)x - 2 Step 2: Estimate y when x=12. Substitute x=12 into the regression equation found in Step 1: y = (3)/(5)(12) - 2 y = (36)/(5) - 2 y = 7.2 - 2 y = 5.2 The equation of the line is y = (3)/(5)x - 2 and the estimated value of y when x=12 is 5.2.
