The graph of the piecewise function includes
(1) a straight line passing through point (-3, 0) and stopping at point (0, 3) with an unshaded small circle at the end of point (0, 3) and an arrow at the other end.
(2) a shaded small circle at point (0, 5), and
(3) a straight line starting at the point (0, -1) and passing through the point (2, 3) with an unshaded small circle at the point (0, -1) and an arrow at the other end.
Positive 28 because to negative will equal a positive number
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
