Exploring Slope from Graph and Formula

This video tutorial explains how to find the slope from two ordered pairs using two methods: graphically and algebraically. The graphical method involves plotting the points on a graph and calculating the rise over run. The algebraic method uses the slope formula, which is the change in y over the change in x. The video demonstrates both methods step-by-step, ensuring a clear understanding of how to calculate the slope.

What are the two methods mentioned for finding the slope?

• Using a calculator and graphing

• Graphing the points and using the slope formula

• Using a ruler and a protractor

• Using a table and a graph

What is the formula for finding the slope?

• m = (x2 - x1) / (y2 - y1)

• m = (y2 - y1) / (x2 - x1)

• m = (y1 - y2) / (x1 - x2)

• m = (x1 - x2) / (y1 - y2)
