How do you graph #x-4y=18#?
Graph as shown below:
One way of doing this is by finding two points on the graph, then connecting them up, so here we will find two points:
Now plotting these points on a graph:
Now joining these points up to yield a line graph:
Then there is our line, this will only really work for lines, when you advance further you will study things called quadratics, these are more difficult to graph!
