1. Find the slope of the graph
A.) − 5 2 B.) − 2 5
C.)
D.)

2. Slope from 2 points
I will be able to find the slope of a line when given two points. I will beat my partner in math Tic-Tac-Toe!

3. Say we are given 2 points:
(x1,y1) and (x2,y2)
Slope is still
m= 𝑅𝑖𝑠𝑒 𝑅𝑢𝑛
Rise= y2-y1
Run= x2-x1
m= 𝑦 2 − 𝑦 1 𝑥 2 − 𝑥 1
All any of this means is: Subtract the first y from the second y
Then subtract the first x from the second Then divide the new y by the new x!

4. Example 1
(3,15) and (5,25)

5. Example 2
(-10, 4) and (8, 3)

6. Example 3
(3,10) and (4, 9.5)

7. Example 4
(5,3) and (18,3)

8. 5 0 −8 0 𝐴𝑁𝑌 𝑁𝑈𝑀𝐵𝐸𝑅 0 m=0 VS m=undefined 0 7 0 −3 0 𝐴𝑁𝑌 𝑁𝑈𝑀𝐵𝐸𝑅
m=0 means our graph is a flat line going left to right!
We get m=0 from a problem like
0 7
0 −3
0 𝐴𝑁𝑌 𝑁𝑈𝑀𝐵𝐸𝑅
m=Undefined means our graph is going Up and down.
We get m=undefined from a problem like
5 0
−8 0
𝐴𝑁𝑌 𝑁𝑈𝑀𝐵𝐸𝑅 0
