Checking solutions of two-variable linear inequalities

The  exercise appears under the Algebra I Math Mission. This practices checking whether an ordered pair is a solution of a two-variable linear inequality, both graphically and algebraically.

Types of problems
There is one type of problem in this exercise:
 * 1) Which of the ordered pairs ___ and ___  is a solution of the inequality represented by the graph below?: This problem asks the user to find which ordered pair(s) are a solution to the inequality of the graph below.

Strategies
Basic knowledge of linear inequalities are required for this exercise.
 * 1) User can graphically check whether a pair of values $$(x,y)$$ is a solution of an inequality by checking whether the point with the coordinates ($$(x,y)$$ lies in the shaded area of the graph representing the inequality.
