Positive and Negative Slopes of Lines

With the use of the handheld computers, students discovered how lines can be sloped in different directions and related this to the original equations of the lines. Students discovered lines with a positive x value slope in one general direction (from bottom left to top right) while equations with a negative x value slope in the opposite direction (from top left to bottom right). Equations with the same x value will be parallel.
