1. Determine which of the ordered pairs are solutions to the system of inequalities below and which are not.

Graph the system of inequalities. Introduce slack variables to convert the system of inequalities to a system of equations, and find all the basic solutions of the system. Complete the table listing each basic solution, the corresponding point on the graph, and whether the basic solution is feasible. Complete the table of basic solution to the system of equations below. (Simplify your answer. Type an ordered pair for each intersection point.)
