-ab b Consider the line y = ax + b in R. Show that the point (x, y) = (a1, a+1) is the closest point on the line to the origin. Hint: Let (x, y) be an arbitrary point on the line and minimize the squared distance from this point to the origin over all choices of x and y. -ab b Consider the line y = ax + b in R.
