Graphing Lines

Type: Learning Activity


In this PhET activity, students will explore the world of lines and investigate the relationships between linear equations, slope, and graphs of lines. The learning goals for this activity will be to explain how the slope of a graphed line can be computed, graph a line given an equation in either slope-intercept or point-slope form, write an equation in slope-intercept or point-slope form given a graphed line, and predict how changing variables in a linear equation will affect the graphed line. This activity should be used to help teach a lesson on graphing linear equations. This PhET activity can be downloaded and assigned to Google Classroom.

Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery. 

If the teacher does not have a PhET account, he/she can create a FREE account. (More information on how PhET works can be found at Getting Started.)
