Day 4: Students will review linear inequalities. Linear inequalities are when you have an equation that you need to solve and then graph. Then, you shade either below or above the line.

Quiz:

1. Graph the following equation: y>2x+1.
2. Graph the following equation: y<2x+1.
3. Graph the following equation: y<3x-2.


Answer Key:

1.

You start at 1 and everytime you go up 2 over 1 and place a dot. Shade above the line because y is greater than 2x+1.
2.

You start at 1 and everytime you go up 2 over 1 and place a dot. You shade under the line because y is less than 2x+1.

3.

You start at -2 and everytime you go up 3 over 1. You shade under the line because y is less than 3x-2.
