Finding Slope from a Graph: Key Concepts and Examples

The video tutorial explains the concept of slope, a key topic in GED math tests. It covers the definition of slope as a measure of steepness, how to identify and use the x-axis and y-axis for calculations, and the process of calculating slope using the rise over run method. The tutorial also provides guidance on selecting points on a graph and includes an example problem to demonstrate the calculation and reduction of fractions.

Why is slope an important topic in GED math tests?

• It is a part of geometry.

• It is used in real-life applications.
