Session 5, Part B:
Slope
In This Part: Thinking About Slope | Comparing Slopes | Slopes and Architecture
|
Here are graphs of nine different lines. Look at the equation and the slope of each line. What changes when the slope becomes positive or negative, and when slope is larger or smaller than 1?
|
 |
|
Problem B5 |  |
Consider this line. What are the coordinates of the points R and S?
|
|
| |
|
Problem B6 | |
Find the slope of the line through points R and S.
|
|
|
| |
|
Problem B7 | |
Many people describe "slope" as a measure of the "steepness" of a line. Look at the two graphs below. Which line has larger slope? Which line appears to be steeper? Explain what is happening. Note 9

Is there anything about the graphs that makes comparison more difficult? Close Tip |

|
Do the following problems on graph paper:
|
|
|
| |
|
Problem B8 | |
On one graph, create three different lines with slope 2. Describe what is the same and what is different about these graphs. Note 10 |
|
|
| |
|
Problem B9 | |
On one graph, create three different lines with negative slope. Describe what is the same and what is different about these graphs. |
