2. The two lines at the right are parallel. How do their slopes compare?

3. Draw a line that is parallel to the given line. Calculate the slope of both lines. What did you find out about the slopes?

4. Draw a line that is parallel to the given line. Calculate the slope of both lines. What did you find out about the slopes?

5. Draw a line that is parallel to the given line. Calculate the slope of both lines. What did you find out about the slopes?

7. If two lines are perpendicular notice there is a different relationship between the slope of the two lines. If one line has a positive slope, then a line perpendicular line to the first line must have what type of slope? What happens to the rise and run from the first slope?
