Copy of Solving Systems of Equations Graphically
Use the sliders to change the slope and the y intercept.
Can you find a spot where the two lines are parallel? What did you set the slope as? What did you set the y-inercept as?
Can you find a spot where two lines are perpendicular? What did you set the slope as? What did you set the y-intercept as?
Can you think of a general rule for when lines will be parallel?
Can you think of a general rule for when lines will be perpendicular?
Can you think of how we can use similar triangles to help us in proving that lines are parallel? Explain your ideas.
