Graph each solution set on a rectangular coordinate system.

  

Two linear inequalities are graphed on the same coordinate axes in the illustration. The solution set of the first inequality is shaded in red, and the solution set of the second in blue.

  

a. Determine from the graph whether (3, –4) is a solution of either inequality.

  

b. Is (3, –4) a solution of the system of two linear inequalities? Explain your answer.
