PhET
Type: Learning Activity

Overview:

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.
