Give reasons for your answer.
O y' = 8(x + y) – 1 = 0 on the lines x = 0 and y = 0, and y' > o for o < x < T/8, 0 < y < T/8.
O y' = 8(x + y) - 1 = 0 on the line y = -x + 1/8, and y' = -1 on the line y = -x.
O y' = 8(x + y) - 1 = 0 on the lines x = 0 and y = 8.
O The slopes at each point are independent of y, so the slopes are the same along each line parallel to the y-axis. Note that for y = 8, y' = 0.
O The slopes at each point are independent of x, so the slopes are the same along each line parallel to the x-axis. Note that for y = 8, y' = 0.
