Describing Positive and Negative Slopes

The video tutorial explains how to describe positive and negative slopes using directed measurements. It begins by reviewing the concept of slope as the ratio of rise over run. The lesson introduces directed counting, emphasizing the importance of direction when measuring rise and run. By using examples, the tutorial demonstrates how to calculate slopes with directed counting, showing that the slope remains consistent despite changes in direction. The video concludes by highlighting the differences between positive and negative slopes and the importance of direction in slope calculations.

Describe how directed counting is used to find the slope.

How can you tell the difference between two lines with slopes of 1/2 and -1/2?

What is the slope of a line if the rise is -2 and the run is 3?
