Students construct a series of GeoGebra applets that investigate the parameters, gradient and intercepts of straight lines. They reinforce this knowledge with Microsoft Math 3.0.

## NSW syllabus outcomes

(MA4-11NA) creates and displays number patterns; graphs and analyses linear relationships; and performs transformations on the Cartesian plane

(MA5.1-6NA) determines the midpoint, gradient and length of an interval, and graphs linear relationships

(MA5.2-9NA) uses the gradient-intercept form to interpret and graph linear relationships

(MA5.3-8NA) uses formulas to find midpoint, gradient and distance on the Cartesian plane, and applies standard forms of the equation of a straight line
