# Graphing Linear Inequalities

**AIM: **SWBAT graph a system of linear

inequalities on the coordinate plane

**DO NOW:
**Find the slope & y-intercept:

**HW:
**P. 434#8, 9, 10,12

Assessment Packet DUE MONDAY!!!

**EXAM MONDAY!!!**

**10.8 GRAPHING LINEAR INEQUALITIES**

**Example:**

You will graph these just like lines :

- Put it in STANDARD FORM

- Find the SLOPE and Y -INT.

- Use the y-int. as 1^{st} point and move to the next

- points using the slope

What’s different about them ?

- If inequality has < , > } | |

- If inequality has < , > } |

- SHADING (just like regular inequalities:

A) Pick a TEST POINT on either side of

the line (0,0) is the best when available

B) Plug it into the inequality to determine if

it is a solution or not

If yes, you shade IN
THE DIRECTION

OF THE TEST POINT

If no, you shade IN
THE OPPOSITE

DIRECTION OF THE TEST POINT

The solution , labeled as “S” is where the 2 shadings

overlap!!
