A gardener lays a straight sprinkler pipe across a rectangular lawn. One end is fixed at A(−8, −3). The midpoint of the pipe is at M(0, 5) on the y-axis.
(a) Find the coordinates of the other end B of the pipe.
(b) Determine the length of the pipe.
(c) If every point on the pipe is shifted 3 units upward, write the new coordinates of A and B after the shift.
