Exercise 8 Page 259

Another solution has to lie within the shaded area or on one of the solid boundary lines.

Example Solution: (3,5)

Practice makes perfect

To name a different solution than (2.5,5), we have to place a point inside the shaded area or on one of the solid boundary lines. Let's plot an ordered pair other than (2.5,5) in this area and read its coordinates.

solution point

Since the solid boundary line is a part of the solution set, (3,5) is another solution of the system.
