Can you find sets of sloping lines that enclose a square?
Collect as many diamonds as you can by drawing three straight lines.
Investigate what happens to the equations of different lines when you reflect them in one of the axes. Try to predict what will happen. Explain your findings.
How does the position of the line affect the equation of the line? What can you say about the equations of parallel lines?
Investigate what happens to the equation of different lines when you translate them. Try to predict what will happen. Explain your findings.
In abstract and computer generated art, a real object can be represented by a simplified set of lines. Can you create a picture using mathematical instructions?
