1. A Lesson on Slope

2. Imagine yourself...

3. What is the meaning of this sign?
A) icy road ahead
B) steep road ahead
C) curvy road ahead
D) trucks entering highway ahead
Hear the answer.

4. Objectives The student will be able to:
1) define slope as “rise over run.”
2) explain how to determine the slope of a staircase or a handicap ramp.
Hear the objectives.

5. Slope is the steepness of a line.
It can also be defined as rise over run (vertical change over horizontal change).
Example
Given the ordered pairs (-2, -2) and (4, 1), find the slope of the line that passes through these points.

6. Determine the slope of the line.
Graph the points (-2, -2) and (4, 1) and apply “rise over run”. 6 3
rise/run = 3/6 = 1/2
Hear an explanation.

7. How would you determine the slope of the staircase?
Hear an explanation.

8. Time for your job interview!
Legally, handicap ramps cannot rise more than 1 inch for every 12 inches of run.
How would you determine if the slope of the ramp below is legal?
Hear an explanation.
