**How it works ?**

**A SOLUTION to a linear inequality of 2 variables is an ordered pair ( x, y) whose coordinates satisfy the original inequality (i.e. make the original inequality true.) **

**For example, note the point (5, 3) shown in the applet below. **

**The graph of the inequality 1x + 1y >= 0**

**is also shown.**

**(5, 3) is a SOLUTION ****to the inequality 1x + 1y >= 0** because

1(5) +1(3)>=0

5 + 3 >=0

8>=0 ==> which is TRUE!

Any point (*x*, *y*) that does NOT satisfy the original inequality (that is, does NOT make the original inequality true) is said NOT to be a solution to the given inequality.

How many solutions (*x*, *y*) does the graph of an linear inequality of two variables have?
