Test if Two Lines are Parallel, Perpendicular or None

This lesson plan is to explain how can we tell if two lines are parallel or perpendicular or none, just by looking at their equations without drawing them on the grid. Below is the lesson plan;

When it comes to equation of lines Always Keep SLOPE in Mind. Can you get it from the equation? If not What should you do to find the slope of the line. Make it the part of your thinking process when working on equations of lines or line geometry, it will show you a path to the solution.

The above lesson plan is perfect for GRADE 9 and GRADE 10 Math Students.
