1. How do we measure the “steepness” of a graph or line?

2. “Steepness” of a graph is called…
SLOPE!
How do I find the slope of a line?

3. How to find the slope of a line when given a graph
Step one: Identify two points that you know for sure are on the line. 4
Step two: Draw in a “slope triangle.” 2
Step three: Identify the base and height of the triangle (from left to right).
Step four: Write the dimensions of the triangle in a fraction with the “rise” as the numerator and the “run” as the denominator.
= ½

4. How to find the slope of a line when given a graph
Up or Right = Positive
Down or Left = Negative -6 2
= -3/1 = -3

5. Examples: Find the slope!
-1/6
3/2 1
