Click on the tools above to create points. Click on the third button to connect these to make a line.
Click on the equation and change to slope intercept form.

1) What is the equation of the above linear equation in slope intercept form?
2) Create a line parallel to the given line. Write the equation in slope intercept form.
3) Create a line perpendicular to the given line. Write the equation in slope intercept form.
4) What do you notice about the slopes of the equations you got for questions two and three?
5) Make a conjecture about parallel and perpendicular lines.
