CAS Mathematics 1.2 Demonstrate an understanding of the features of graphs
Linear functions written in any form
To graph lines which have equations that are written in a form other than y = mx + c, for instance 2x + 3y – 6, use one of the following methods:
- gradient/intercept method (first rearrange into y = mx + c form)
- two-intercept method (put y = 0 to find x-intercept, and x = 0 to find the y-intercept)
- plotting points.
