This lesson explores the Cartesian coordinate system. Students begin by naming the location of points with an ordered pair and plotting points. They see and apply the formula for finding the midpoint of a segment using the coordinates of its two endpoints. Students also learn the equation of a vertical and horizontal lines, and how its corresponding inequality is graphed as a shaded region. The lesson concludes with identifying graphs of the intersection of a horizontal and vertical inequalities.
