This GeoGebra file is a exploration of topics in the Linear Relations unit for the 10C curriculum. The file allows the user to explore the relationship between the slope-intercept form equation, the y-intercept, and slope of a line. Furthermore, the user may use the sliders to change the slope and y-intercept to change the equation and direction of the line. As well, the slope tool allows the user to see the change in the rise and run as the sliders are moved. Lastly this file can be extended to explore the equation of parallel and perpendicular lines through a point or writing equation of a line given the slope and a point to find the b-value.
