Answer to Initial Practice: Determining Whether the Slope of a
Line is Positive, Negative, Infinite or Zero

  1. In the figure below, which line(s) (R, S, or T) has a positive slope? Which one(s) has a negative slope?

The line T has a positive slope.
Both line R and line S have a negative slope

  1. In the graphs below (a through f), which contain(s) a line with a positive slope? A negative slope? Slope of zero? Infinite slope?

(a) negative slope
(d) infinite slope		 (b) slope of zero
(e) positive slope		 (c) negative slope
(f) slope of zero
