## 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*.
