Parallel LinesGo to the Math Open Reference website and work with the parallel lines applet to create two examples of parallel lines, one with positive slopes and one with negative slopes.
Click on the “Full screen” button, and then move the lines by dragging the points. You will see when the lines are parallel because the slopes will be the same.
Write one example and one non-example of equations of parallel lines in your notes. Remember the slopes should be the same. (Hint: Drag your line so that you can read the y-intercept clearly.)
Go to the Math Open Reference website and work with the perpendicular lines applet to create two examples of perpendicular lines.
Click on the “Full screen” button, and then move the lines by dragging the points. You will see when the lines are perpendicular because the slopes will be negative reciprocals.
Write one example and one non-example of equations of perpendicular lines. Remember the slopes should be negative reciprocals. (Hint: Drag your line so that you can read the y-intercept clearly.)
