Calculating Slope from Various Representations

The video tutorial covers four methods to calculate slope: from equations, graphs, tables, and using the slope formula. It explains how to identify slope from equations by looking at the coefficient of x, how to use rise over run on graphs, how to calculate slope from tables using Delta y over Delta x, and how to apply the slope formula for two points. The tutorial emphasizes understanding the concept of slope and provides practical examples for each method.

Which of the following is NOT a method to calculate slope mentioned in the video?

• From a circle

• From a graph

• From a table

• From an equation
