Using Your Algebra Skills 3

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

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

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

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

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?

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

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