Linear Equations

Cartesian Planes

Students locate an ordered pair in any one of the four quadrants on the Cartesian plane. They assign ordered pairs to given points on the Cartesian plane. They represent transformations in the Cartesian plane. They solve linear equations and graph linear relationships on the Cartesian plane. They find the distance between two points on the Cartesian plane and the gradient and midpoint of a line segment. They sketch linear and non-linear relations.
