To state: how can we determine whether an ordered pair is a solution of a system of linear inequalities.
Explanation of Solution
Put the x-coordinate and y-coordinate of ordered pair in given system of inequalities, if they satisfy then, the given ordered pair is solution of given system of inequalities.
For example take system of inequalities such as
And we have to check whether (-3, -3) is solution this system of inequalities or not.
Putting this value in inequality
This satisfies.
Again putting (-3, -3) in inequality
This also satisfies.
Hence we can say that (-3, -3) is a solution of given system of inequalities.
