Graphing 9 - Intro to slope

In this lesson, we learn about the concept of slope and how to find the slope of a line by looking at its graph. The slope is a number that measures the slant of a line and is represented by the letter M. Depending on the slant of the line, we can determine whether the slope is positive, negative, zero, or undefined. We can compute the slope by using the idea of rise over run and choosing any two points on the line.

This covers the concept of slope, what it means and how to find the slope of a line by looking at its graph. This is part 9 of a series of videos about graphing lines.

• How do you find the slope of a line?
• What is the definition of slope?
• How do you know if the slope of a line will be positive or negative?
• What is the slope of a vertical line?
• What is the slope of a horizontal line?
• When is the slope of a line undefined?
• When is the slope of a line zero?
• What is a cheer or song that helps you remember whether the slope of a line will be positive, negative, zero, or undefined?
• How do you use rise / run to compute the exact slope of a line that is graphed?
• Does it matter which two points you pick to find the slope of a line?
