A Slope of One   |
|
  |
    Listen to a slope of one. Then, listen again.     We'll use this as the unit of measure of slope. We'll judge other slopes in comparison to this.     Listen again to a slope of one then describe in detail to yourself what you've heard.     |
Slope -- A Measure of Change   | |
  |
    If your description involved two ideas, a sequence of notes (increasing in frequency) and a speed at which the notes are sounded, it may be used to relates the two ideas. Slope does that. Slope relates or compares two ideas and how each changes relative to the other.     Slope may be used to compare changes in distance to that of time, or changes in speed compared to time, or changes in size compared to time, or vertical distance compared to horizontal distance, or function value compared to inpute value.     First, skip reading an accurate technical definition of slope and consider its purpose and the numerical scale used to measure it.

The Scale Called Slope   |
|
  |
    You've listened to a slope of one but you've not listened to a slope of zero. Using two measurements, a scale or guage is possible. Two measurements are required -- the zero and the one. With these established, other measurements follow.     Listen to a slope of zero and to a slope of one.
