A graph plots Income in thousands against Saving, Investment, and Government spending. The horizontal axis is labeled Income in thousands and ranges from 0 to 5.2, in increments of 0.4. The vertical axis is labeled Saving and Investment and ranges from negative 200 to 300, in increments of 100. Two parallel lines labeled I and I plus G originate from (0, 100) and (0, 200) respectively and run parallel to the horizontal axis. A curve labeled S originates from (negative 150, 3.3) and follows a positive slope while passing through (4, 0) and intersecting the I curve at e (4.4, 100), and the I plus G curve at b (4.8, 200). Two vertical dashed lines extend from 4.4 and 4.8 on the horizontal axis to curve S. This economy is at point a. This figure depicts an economy in: Group of answer choices neither short-run nor long-run equilibrium. short-run equilibrium only. both short-run and long-run equilibrium long-run equilibrium only
