Slide point [i]R[/i] up and down the y-axis. How did the coefficients of the equation of the line change?
Next, slide the slider to rotate the line around point [i]R[/i] without moving point [i]R[/i]. How did the coefficients of the equation of the line change?
What is the general equation for this type of line? What do changing each of the coefficients do to the graph of the line?
