1. Slope Intercept Form
Graph an equation using the slope and the y intercept and write an equation of a line.

2. Slope and y intercept
y = 3/2x - 4
(0, ?)
y = 3/2x + 3
(0, ?)

3. Vocabulary y – intercept : where the line crosses the y axis.
Slope – intercept form: y = mx + b
m = slope
b = y – intercept

4. Identify the slope and y - intercept
y = 3x – 2
Y = -2x – 8
M = 3
B = -2
M = -2
B = -8

5. Graph
y = 1/3x + 5

6. Graph
y = 2/3x - 6

7. Graph
y = 2/5x + 1

8. Graph
y = -x - 1

9. What are the slope and y – intercept of y = x?

10. Write an equation of the line. Use slope intercept form. Y = mx + b
What is the
y – intercept (b)? -2
What is the
Slope (m)? 2
y = 2x - 2

11. Write an equation of the line. Use slope intercept form. Y = mx + b
What is the
y – intercept (b)? 3
What is the
Slope (m)? 1
y = x + 3

12. Group Challenge
Why is it impossible for any point to lie on both y = 3x + 5 and on y = 3x – 2? Use a graph to illustrate your explanation.

13. Write an equation of the line. Use slope intercept form. Y = mx + b
What is the
y – intercept (b)? 4
What is the
Slope (m)?
1/2
y = 1/2x + 4

14. Group Challenge
Explain why it is impossible for any for any point to lie on both y = 3x + 5 and y = 3x -2? Use a graph to illustrate your explanations.
