Bypass the table and go straight to the graph. A short video shows one example of graphing a direct variation equation with a negative slope by using the same method as graphing an equation in slope-intercept form. Pupils see it's easy to plot the slope from the origin to create the graph.
- Compare the method of graphing with graphing using a table
- Provide a set of practice problems with both positive and negative slopes to graph
- Individuals should be able to graph lines using slope-intercept form
- Uses colors to graph steps of the solution process
- Graphs multiple points on the plane to show the extent of the complete line
