PhET
Type: Learning Activity

Overview:

In this PhET activity, students explore the slope-intercept form of a line and connect the slope and y-intercept to the equation of the line. The learning goals for this activity will be to graph a line given an equation in slope-intercept form, write an equation in slope-intercept form given a graphed line, predict how changing the values in a linear equation will affect the graphed line, and predict how changing the graphed line will affect the equation. This activity can be used to help teach a lesson on graphing linear equations. This PheET activity can be downloaded and assigned to Google Classroom.
