In the following Try This activity you will explore slope at various points along different graphs of lines and curves.

 

 

Try This 1

 

Complete the table for Slopes 1, 2, and 3 by finding the slope for multiple points on each graph.

 

Slopes of Lines
Slope 1			Slope 2			Slope 3
Point 1	Point 2	Slope	Point 1	Point 2	Slope	Point 1	Point 2	Slope
(−6, −8)	(2, 8)	2

1. What did you notice about the slopes of lines 1, 2, and 3? Did you observe any patterns?
