Today we have been doing some research on the internet of what an Ex line , a why line,a Discrete graph and a Continuous graph is.An Ex and a Why is 2 lines on a graph , an ex is a Horizontal line and the why is the Vertical line on the graph.The Discrete graph is a graph that work with the Continuous chart. The Continuous graph adds on and on but the Discrete graph take away and away.

Here are some drawing of some graphs with the Ex and the Why.
