12. What Type of Slope is Shown?
Positive Slope
Negative Slope
Zero Slope
No Slope/Undefined

13. Slope
Slope: the rate of change between any two points on a line. It is a measure of the steepness of the line.
Slope can be positive, negative, zero, or undefined. You can find slope using 2 points.
The slope between any 2 points on a line is constant

14. Rise (y- axis) = Going up will be a positive value, going down will be a negative value
Run (x-axis) = Going right will be a positive value, going left will be a negative value
m= rise
run

15. rise = -4
m= rise
run
−𝟒 −𝟓
run = -5
m=4/5

16. 1) Determine the slope of the line.
When given the graph, it is easier to apply “rise over run”.

17. Determine the slope of the line.
Start with the lower point and count how much you rise and run to get to the other point!
rise 3 = =
run 6 6 3
Notice the slope is positive AND the line increases!

18. Slope of a Graph First pick two points on the line
The points need to be where the lines cross so they are integers
2. Then find the rise and run
3. Determine if the slope of the line is positive or negative
Rise = 2
Run = 3

19. Slope of a Graph First pick two points on the line
The points need to be where the lines cross so they are integers
2. Then find the rise and run
3. Determine if the slope of the line is positive or negative
Rise = 10
Run = 2
