public class SlopeInterceptLine
extends AlgebraicLine

This class represents a line in slope-intercept form: y = k x + d. Instances are immutable. Not all possible lines in the 2D plane can be represented. A SlopeInterceptLine is merely a AlgebraicLine with a special constructor and getter methods for k, d. See Sec. 10.1 and Appendix F.1 of [1] for details.
