Previous Problem Problem List Next Problem (1 point) Use a least squares approximation to find the best linear fit (i.e., the best line) L(t) = C + Dt , that is closest, in the sense of least squares, to passing through the through the following data points: (t1, b1) = (-2, 12) , (t2, b2) = (0,9) , (t3, b3) = (2,0) , (t4, b4) = (4, -5) . What are the y-intercept C and the slope D of this line
