1. Understanding
Slope

2. Slope is a
measure of
Steepness.

3. Types of Slope
Zero
Negative
Positive
Undefined or
No Slope

4. Slope is sometimes
referred to as the
“rate of change”
between 2 points.

5. used to represent slope
The letter “m” is
used to represent slope
in the linear equation
y = mx + b

6. If given 2 points on
a line, you may find
the slope using the
formula m = y2 – y1
x2 – x1

7. The formula may
sometimes be written
as m =∆y . ∆x
∆ represents CHANGE

8. Find the slope of the line through the points (3,7) and (5, 19). x1 y1
m = 19 – 7
5 – 3
m = 12 2
m = 6

9. (3, 4) and (-6, -2)
m = -2 – 4
-6 – 3
m = -6 -9
m = ⅔

10. of a line, you can easily find the slope and y-intercept.
If given an equation
of a line, you can easily find
the slope and y-intercept.

11. equation and locate the m
Look at the linear
equation and locate the m
and b in the form
y = mx + b.
slope
y-intercept

12. y = 3x + ½ Find the slope and y-intercept of the following equations.

13. of a line, you can find the
If given the graph
of a line, you can find the
slope by finding
the rise over run.

14. rise = 4
m= rise
run
run = 5
m= 4/5

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

16. If either the rise OR the run is negative, then the whole slope is negative:
