Finding Slope from a Slope Triangle

Question 1

Without changing anything in the graph, what is the slope of Line AB? How do you know?

Question 2

Move Point P from (10,4) to (8,2). How does the new slope triangle compare with the original?

Question 3

What transformation or series of transformations maps the original slope triangle onto the new one?

Further Exploration

1. Explore what happens when you move Point P to other locations. Do the relationships you saw when you first moved Point P continue to hold? 2. You can also change the line by moving Points A and B and explore what happens when you move Point P.
