Slope

Slope is a measurement of how quickly a quantity is changing. It tells you how much the graph changes per unit. Positive slopes, negative slopes, zero slopes, undefined slopes.

Level 1: unit run e.g. 1, 2, 3, 4

Level 2: run greater than one e.g. 4/2, 6/2, 6/3, 10/2


 * slope = rise/run**

Level 3: fractional slopes

4/3, 3/4, 2/3, 1/2, 2/1, **whole number slopes**, **negative slopes**

Level 4: slope from co-ordinates
