SLOPE

Finding Slope of a Line Using A Graph

Multiple Choice

What is another name for slope?

• initial value

• linear

• rate of change

• graph

In the formula y=mx+b

m = slope

There are four types of slopes.....

Multiple Choice

Which is not one of the four types of slopes?

• positive

• equal

• negative

• zero

• undefined

How to find the slope:

• 1. choose two points on the line

• 2. find the change in y-values (rise). if you move up the change is positive & if you move down the change is negative

• 3. find the change in x-values (run). if you move right the change is positive & if you move left the change is negative

• 4. slope = rise / run

Multiple Choice

Slope can be found from a graph using...

• run / rise

• rise / run

• rise / fall

• fall / rise

Together:

• Rise: 3

• Run: - 4

• Rise / Run: 3 / - 4

• Slope: - 3 / 4
