Graphing Method # 2
Using the Intercept Form

There are two intercept for any linear equation.

x intercept => where the line crosses the x axis.

y intercept => where the line crosses the y axis.

eg. graph the equation

* substitute 0 for x and then substitute 0 for y.

Using the intercept method.

Method # 3

Slope- Intercept Form

Step :
1.) Equation must be put into y= mx + b form.
ex. graph x- 2y = 2 ( using the intercept form.)

m = 1/2 = slope
b = -1 y intercept

2.) Plot the y intercept.
3.) Use the slope rise/run to find the second point from "b".

- and when graphing it, from point "b" rise 1/2 then run 2 place.

Homework:

• Exercise # 11 and 12

And dont forget about the following dates:

• October 13, 2006 - Quiz- 3 Graphing Methods.
• October 17, 2006 - Slide project is due. (Ms. Armstrong changed it due to not having enough time because of the fire drill incident.)
• October 19, 2006 - Analytic Geometry

And the next blogger is Emman.
