AlgebraSLOPESSummaryThe important information in this chapter is summarized below.Slopes SummaryFor a straight line, slope is equal to rise over run, orSlopeRiseRunChange in yChange in xDyDxSince slope m is a measure of the steepness of a line, a slope has the followingcharacteristics:1. A horizontal line has zero slope.2. A line that rises to the right of vertical has positive slope.3. A line rising to the left of vertical has negative slope.4. A vertical line has undefined slope because the calculation of theslope would involve division by zero (Dy/Dx approaches infinity asthe slope approaches vertical).Rev. 0 Page 89 MA-02
