Unit 5: Day 5

Day 5:  State and Define the Objective 

Students will graph linear inequalities. 

This objective is referring to the equations and inequalities which determine which points are plotted on the X and Y intercepts. 

Day 5: Pictures and Graphs Relating to Objective 

This graph represents the linear inequalities by illustrating the greater or lesser values, which are shaded. 

This graph illustrates the dotted line separating the greater or lesser then values of the inequality. 

This shows the inequality itself. Inequalities must first be organized into the format of an equation so that you can solve for the X and Y intercepts. 

Quiz Time!

1. Graph the equation y<1x+2

2. Graph the equation y> 2x +1

3. Graph the equation y>4x-1

Key:

1.

The graph has a dotted line and is shaded below because it's not inclusive of the line and is less than.

 

2.

The graph has a solid line and is shaded above because it's inclusive of the line and is greater than.

 

3.

The graph has a dotted line, because it is not inclusive of the line, and is shaded above for greater than.
