Exercise 1 Page 260

Where does the point fall on the graphed solution sets?

See solution.

Practice makes perfect

There are two ways to know for sure that an ordered pair is a solution to a system of linear inequalities:

If you graph the system, an ordered pair is a solution if it falls within the overlapping shaded area.
If you substitute the ordered pair into all the inequalities of the system, it satisfies each inequality individually.
