Parallel line discovery
following direction below. start with the following for slope and y intercept. slope = 2 y-intercept = 0 The next time change to something else. make sure you try a fraction at least once.
Enter 2/3 in the first text box for the slope of the blue line. Enter 5 in the second text box for the y-intercept of the blue line. Now use the sliders to find the parallel and answer the following questions. 1. What is the relationship between the slopes of each line? 2. What do you notice about the equations of the line and its parallel? 3. Will this always be the case for any slope and y-intercept? Try several other slopes and y intercepts to confirm.
