1. Warm-Up ~ Unit 3 Day 7
1. Write the equation in slope intercept form of the line that passes through the points (1,-5) and (-3,7). 2. Write the equation in slope intercept form of the line with a slope of 0 and passes through the point (4, 6). 3. Solve for the value of h, given the line passing through the points (2, h) and (-4, 4) has a slope of ½.

3. Parallel and Perpendicular
Unit 3 – Linear Equations

4. Parallel || Tell me examples of parallel lines in the Real World?
Characteristics ~
Parallel lines have the same slope, but different y- intercepts.
Symbol:

5. Are these Parallel? 1) y = 4x-3 and y = 7+ 4x
Yes No
No – They are the same line

6. Perpendicular ⊥ Tell me examples of perpendicular lines in the world?
Characteristics ~
Perpendicular lines have slopes that are opposite/negative reciprocals of each other.
Opposite reciprocals mean: -4 and ¼
Symbol:

7. Are these Perpendicular?No
Yes

8. Let’s Put Them Together…
31 Parallel
32 Perp
33 Neither
34 Neither
35 Parallel
36 Perp

9. Creating Parallel Lines
Steps:
Find M
Plug in m and a point
Solve for b.
Rewrite equation
m=2/3 through (2,4)
2. Find the equation of the line that passes through ( - 4 , 3 ) and is parallel to the line 3x+4y= 12

10. Practice
Find the equation of the line that passes through ( - 2 , 5 ) and is parallel to the line 3x-2y= 12
Find the equation of the line that passes through (4, 5) and is parallel to the line - 7x+3y= 12

11. Creating Perpendicular
Steps:
Find M
Create new slope
Plug in new m and a point
Solve for b.
Rewrite equation
m=2/3 through (2,4)
2. Find the equation of the line that passes through ( - 4 , 6 ) and is perpendicular to the line 3x+4y= 12

12. Practice Perpendicular
Find the equation of the line that passes through
( - 2 , 1 ) and is perpendicular to the line 3x+2y= 17
Find the equation of the line that passes through (4, 9) and is perpendicular to the line -2x+3y= 10
