Graphing Linear Inequalities

                     Lesson 1

Problem:     Graph:  y > x - 13   

x	1	2	3
y	-1	0	1

Solution       Put “=” in place of “>” : y = x - 13

                                                            Step 1:                         

Solution        Assume values of x and find out value of y.

Step 2:         

Solution        Show all three points (x, y) on the graph.

Step 3:            Draw line a solid if the inequality is

< or >

                                                            Solution  If the point makes the inequality true, shade that side of the        line. 

                                                            Step 4:

                                                            Solution       If the point does not make the inequality true, shade the   opposite side of the line.

                                                            Step 5: 

Complete      

                                                            Try two practice problems:  

A.

y >  x -  1

B.

y  <  7x -  11
