| Explore the properties
of parallel lines with the LiveMath Notebook at the left. Change
the values of the coefficients in the original equations and watch as the
graphs update online.
What must the coefficients of the second equation change to for the lines to be perpendicular? Remember that perpendicular lines have slopes that are the negative reciprocals of each other. Use the mouse to drag the graph to find point of intersection for non parallel lines, or use the zoom out feature. Click on the rocket ship. |
