In this lesson students will learn to model perpendicular and parallel lines in the mathematical program Geogebra. The students have been learning how to graph linear equations by finding the slope and y-intercept of an equation. They are able to then use this information to graph the line by hand. Following this lesson the students will get the chance to work in the computer lab on the Geogebra program. The students know about the characteristics of perpendicular and parallel lines but they have not gotten the opportunity to graph them on the same coordinate system.
The Geogebra program will help the students graph linear equations more easily than they would drawing it by hand. The students have the ability to manipulate the points and slope more easily than if they were working on paper. Since it takes less time to graph the equations the students have the opportunity to make connections sooner. Geogebra helps the students to visualize the graphical representations of lines in relation to the properties that the equation is showing them. Not only will they be able to explain their reasoning from an equation, but from a graph as well.
