True or False state whether the statement is always true (AT) sometimes true (ST)
or never true (NT)

1.A system of inequalities has a unique ordered pair as a solution.

2. The boundary line is solid when the points on the line are part of the solution

When (0,0) is substituted in the inequality resulting FALSE statement, the half-plane that contains (0,0) is the solution.

4. In graphing linear inequalities, the boundary lines define the limits of the region which represents the solutions to the inequality.

5. A graph of inequality in two variables x and y consist of all points (x,y) whose coordinates satisfy the inequality.​
