Finding the Slope of a Line

Mrs. Piper explains how to find the slope of a graph by identifying two points and using the rise over run method. She provides multiple examples, demonstrating how to calculate and simplify the slope. The video emphasizes that the slope remains consistent regardless of which points are chosen on the line.

What is the first step in finding the slope of a line when given a graph?

• Calculate the rise over run

• Identify two points on the line

• Draw a straight line

• Find the midpoint of the line

How do you calculate the slope of a line?

• Add the x and y coordinates

• Multiply the x-coordinates

• Divide the y-coordinates

• Subtract the y-coordinates and divide by the difference in x-coordinates
