Detailed study guide with exercises, rules, methods etc for how to sketch and interpret straight line functions at senior phase level. Includes eall of the following:

• Fundamental understanding of the Cartesian Plane & associated terminology
• Properties of graphs (discrete, continuous, min & max values, increasing & decreasing)
• Horizontal & Vertical lines
• Standard form
• Sketching using 3 methods (Table, Dual Intercept, Gradient method)
• Gradient (slope) & how to determine gradient using i) a graph or ii) given coordinates
• Perpendicular & parallel lines
• Determining the equation of Straight lines
