Introduction To Slope

Slope is a measure of Steepness.

Types of Slope Positive Negative slope of zero undefined

Slope is sometimes referred to as the “Rate of Change”.

Slope is represented by the letter “m” Why? I have no idea so I just think m for mountains and mountains have slope.

Slope may sometimes be written as m =∆y. ∆x What is ∆ ? The Greek letter Delta which means “the change in”

If given the graph of a line, find the slope by using the “triangle” method to find the change in y OVER the change in x

Change in y = 4 Change in x = 5 m= the change in y the change in x m=

And These

To Review: Create two points on the line where two grid lines meet Start with the point on the left Draw a vertical line until you are even with the second point Then draw a horizontal line to the second point Put the change in y-values over the change in x-values Reduce the fraction
