Activity - Name of Activity

Parallel lines have the same slope and slope of perpendicular lines are the negative reciprocals of each other

Estimated Time

1 Hour

Materials/ Resources needed

Geogebra applet

Prerequisites/Instructions, if any

Students should know that every line is a representation of an equation /relation between variables
Graphing an equation/producing equation by visualising graph
Students should know what is Slope?
Similarity of two triangles
