1. Introduction
To Slope

2. Slope is a
measure of
Steepness.

3. Types of Slope
Zero
Negative
Positive
Undefined

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.
Why?

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

7. 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

8. (3, 4) and (-6, -2)
m = -2 – 4
-6 – 3
m = -6 -9
m = ⅔

9. What if the
numerator is 0?
denominator is 0?

10. If given an equation
of a line, there are
2 ways to find the
slope and y-intercept.

11. One method is to write the equation in slope-intercept form,
which is y = mx + b.
slope
y-intercept

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

13. If given the graph
of a line, find the
slope by using the
“triangle” method to
find the rise over run.

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