- For problem 1, graph the line y = -x for x ≤ 2 and the line y = x for x > 2. At x = 2, plot a closed circle on y = -2 and an open circle on y = 2.
- For problem 2, graph the horizontal line y = 2 for x > -3 and the horizontal line y = -5 for x < -3. At x = -3, plot open circles at ( -3, 2 ) and ( -3, -5 ).
- For problem 3, graph the horizontal line y = -1 for x ≤ -2 and the horizontal line y = 2 for x > -2. At x = -2, plot a closed circle on y = -1 and an open circle on y = 2.
- For problem 4, graph the horizontal line y = -1 for x ≤ -1, the horizontal line y = 1 for -1 < x < 1, and the line y = x for x > 1. At x = -1, plot a closed circle on y = -1 and an open circle on y = 1. At x = 1, plot open circles on y = 1 and y = 1.
- For problem 5, graph the line y = -x + 2 for x ≤ 0 and the line y = (1/2)x + 3 for x > 0. At x = 0, plot a closed circle on y = 2 and an open circle on y = 3.
- For problem 6, graph the line y = x + 2 for x ≤ 2 and the line y = -(1/2)x + 4 for x > 2. At x = 2, plot a closed circle on y = 4 and an open circle on y = 3.
