1. Algebra 6-1 Rate of Change & Slope 6-2 Slope-Intercept Form

2. Warm Up Write in simplest form:

3. Rates of Change HW 1.For number 4 d, what did you find about the rate of change for the different car models? 2.For number 7, how did the scale used affect the data presented? 3.What did you learn from the activity?

4. Journaling What is a journal? Why do we journal? What is important about journaling? How long should it take?

5. How to Journal 1.Write vocab. words without definitions. 2.Identify your vocab. words with a label- D for don’t know, K for know, ? Heard it before but don’t remember. 3.Take notes on Key Concepts. 4.Work through all Check for Understanding Questions. 5.If you can’t do Check for Understanding, take notes and summarize the example.

6. Journal Example for 6-1 Rate of Change and Slope

7. 6-2 Slope- Intercept Form Vocabulary: Linear Equation- y-intercept- Slope-intercept form-

8. Vocabulary Definitions Linear equation- an equation whose graph is a line Y-intercept- the y-coordinate of the point where a line crosses the y-axis Slope-intercept form- linear equation written as y=mx + b slope y-intercept

9. Example 1 What are the slopes and the y-intercept of y= 2x – 3 ?

10. Example 2 Write an equation in slope-intercept form of the line with a slope of 2/3 and a y- intercept of -5.

11. Example 3 Write an equation for the line.

12. Think About It… What does a line on a graph stand for?

13. Ex. 4 Is there another way to graph? How could you graph the equation y=3x-1 using what you just learned?

14. To Summarize: 1.How does changing the value of m affect the graph of a line? 2.How does changing the value of b affect the graph of a line?
