During the past week the Grade 10 Mathematics class has been practicing drawing Linear Functions, by using either the “Table Method” or “Intercept Method”. It really helps to visually see the relationship between the x and the y co-ordinates as they are plotted on the Cartesian Plane.

A function is a mathematical rule by means of which each element of x is associated with only one element of y. It is possible to “draw” these functions on a Cartesian Plane using x and y co-ordinates.
