### Thursday Nov. 30/06

Okay so today we did mental math (number 23), we also heard about Max's big story (He sneezed, heard a squishy noise and fell over). Just to recap the past 2 days...they were both snow days, so if you showed up it was just a work period.

****NOTES****

**Graphing 2D Inequality (the hard way)(in 2 dimensions)**

**>How do I graph something like this?**

**2x+3y>6?**

**step 1**: think of corresponding equation

-2x+3y=6

**step 2**:solve for y

3y=6-2x

y=-2x/3+2

**step 3**:find slope and y intercept

m=-2/3 b=+2

**step 4**:graph corresponding line

**step 5**:which way to shade--TEST A POINT!(If posible choose orgin as a test point)

**REMEMBER**: original inequality....2x+3y>6

(2)(0)+(3)(0)>6

0>6

NO! or FALSE! or WRONG!

-- so shade

*away*from the orgin--**step 6**:what kind of line (dotted or solid line)

We used a dotter line since it was greater or less than

**I tried to put a picture of the graph but it wouldnt load**

**We decided in class today we are having a accelerated math test**

**tomorrow*******Reminder to get your wiki picked if not done already...

**put your last name....when doing wiki projects use spellcheck**

*DONT*Thats it for my post for today.....kiersten
