Chapter 6 - Graphs, linear functions and straight lines
This chapter discusses graphs, linear functions and straight lines.
It contains the following sections:
- section 6.1 - In this section we introduce
rectangular coordinates, graphs and how to locate points on a graph.
- section 6.2 - In this section we talk about linear
functions and their graphs, which are straight lines.
- section 6.3 - In this section we talk about other
types of graphs such as parametric graphs and contour graphs. We also explain how
to solve equations graphically.
