ACCESS - Exploring Slope

The sliders allow you to adjust the rise (horizontal) and run (vertical) distance between the red and blue points. You can also drag the red point to move the line. 

1. What happens when rise and run have the same sign? The opposite sign?

2. What happens when rise is larger than run? When run is larger than rise?

3. Can you get a vertical line? How?

4. Can you get a horizontal line? How?

5. Fill in the blanks below.

When slope is large, the line is _________. 

When slope is small, the line is _________.

rise

run

A = (1, 1)
B: (x(A) + run, y(A) + rise)
a = Line(A, B)
C: (x(A), y(A) + rise)
