1. Bellwork  Rewrite in slope intercept form:  4x + 2y = 8  3x = 4 – 2y

2. Chapter 4.1 October 8, 2014

3. Objectives  You will be able to write and graph linear equations in slope-intercept form.

4. Key Idea: SLOPE-INTERCEPT FORM  The slope-intercept form of a linear equation is y=mx+b  Where m is __________, and b is the ___ ____________.

5. Example  Write an equation of a line in slope intercept form with the given slope and y- intercept. Then graph the equation.  Slope: and y intercept: 3

6. Example  Rewrite 3x-4y=12 in slope-intercept form and graph:

7. Example  Rewrite 4 + 4y = x in slope intercept form and graph:

8. Graph y=-2

9. Example Which equation is right? Y= -2x +2 Y= 1/2x +2 Y= 2x + 2 Y=-1/2x+2 Y=-1/2x -2
