What is the area of the triangle formed by these three 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.
Here's a problem to work at with your graphic calculator or
graph-plotting package on a computer.
If you plot the following lines
the lines will enclose a square.
Can you find other sets of sloping lines that enclose a
