### Slope!!!

With “Real-Life” Examples

• The slope of a line is defined as the rate of change of a function or graph. It can also be thought of as the steepness of a line.

• Before we learn how to calculate and graph slope, we need to understand the different types of slopes and how they behave.

• A line that is increasing as you move to the RIGHT, has a positive slope.

• It can be any value as long as it is greater than 0.

• The larger the number, the steeper the line.

• A line that is decreasing as you move to the RIGHT, has a negative slope.

• It can be any value as long as it is less than 0.

• The larger (more negative) the number, the steeper the line.

• A line that has no slope is a horizontal line.

• Its slope is equal to 0.

• Can you think of other examples of things with no slope?

• A vertical line has what is called an undefined slope.

• Can you think of other examples of things with an undefined slope?

• Is this a positive or negative slope? How can you tell?

• What makes this different than the other positive slope we saw?

• Is this a positive or negative slope? How can you tell?

• What makes this different than the other negative slope we saw?
