We begin graphing systems of simultaneous equation. Before we begin looking at the many graphs you can find out on the Web, a good starting point is to review our knowledge of 2-D graphs. These graphs are known as 2-D because they have two axes. One you are familiar with is the xy-graph, which has an x axis and a y-axis.

Please explain 2 characteristics of graphs with examples.
