Exploring Different Types of Slopes

This video tutorial explains the concept of slope in a linear relationship, describing it as the slant or steepness of a line, also known as the rate of change. It covers positive and negative slopes, illustrating how lines rise or fall from left to right. The video also discusses vertical and horizontal lines, explaining that vertical lines have an undefined slope while horizontal lines have a slope of zero. Examples are provided to clarify these concepts.

What does the slope of a line represent in a linear relationship?

• The slant or steepness of the line

• The curvature of the line

• The length of the line

• The color of the line

How is the slope of a line calculated?
