The following graph shows the solution to which system of inequalities?select one: a. 1 y> −2x+2 b. 1≤y≤3 y≤−2x+2 c. 1≤y≤3 y≥−2x+2 d. y≤3 y≤−2x+2

Looking at the purple area, we see that 1≤y≤3. So we can immediately reject answers (d), (a).

Since the purple area is to the right of and above the sloping line, we choose answer (c).

The correct answer to the whole problem is (c).
