Can you find sets of sloping lines that enclose a square?
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?
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?
Investigate what happens to the equation of different lines when
you translate them. Try to predict what will happen. Explain your
This task requires learners to explain and help others, asking and answering questions.
