4. 3.4 Find and Use Slope of Lines
Equation of a line (y-intercept form):
y = mx + b
Slope y-intercept

5. Slope

6. Types of Slope
Falls
Rises
Vertical
Horizontal

7. Find slopes of lines in a coordinate plane
Example 1:
Find the slope of…
line a:
1st - pick any two points on line a
(0,2) and (4, 6)
(0,2) and (4, 6)

8. Find slopes of lines in a coordinate plane
Example 1:
Find the slope of…
line c:
1st - pick any two points on line a
(0,6) and (4,6)
(0,6) and (4,6)
= 0

9. On Your Own 1: Using the diagram above, find the slope of… line b:
line d:

10. slope
horizontal -1
perpendicular

11. Opposite Reciprocal

12. Identify parallel lines Example 2:
Find the slope of each line. Which lines are parallel?

13. On Your Own 2: Line c passes through (2, -2) and (5, 7).
Line d passes through (-3, 4) and (1, -8).
Are the two lines parallel? Explain how you know.

14. For group quizzes..
While you are working in groups, everyone is still responsible for showing their work on their own quiz
No one is aloud to talk to anyone that is not in their assigned group.
If you do, you will get a zero on your daily quiz.
