Slope Concepts: Rise over Run Explained

This video tutorial covers the concept of slope, defined as the ratio of rise over run, and explains how to calculate it using points on a line. It discusses different types of slopes, including positive, negative, zero, and undefined slopes, and demonstrates how to find the slope from a graph. The tutorial also guides viewers on drawing lines with a given slope, emphasizing the importance of plotting points accurately and understanding the direction of the slope.

What does the term 'slope' refer to in mathematics?

• The horizontal distance between two points

• The vertical distance between two points

• The ratio of vertical change to horizontal change

• The angle between a line and the x-axis
