Step1 A line with slope in through (4, I") has equaoh y = mx + - -. (Hint: Solve for 1" b.) (I. )0 Step 2 111a yintereept is T 4m and the xintercept is Iv -+|., -. m mp3 111erefore, the area to be minimized is given by earmew) A(m) Since no is negative, then solving A' = 0 gives m = I V . 4 7 So the equation nfthe line which minimizes the area is
