1. Plotting straight line graphs In order to plot straight line graphs we need to substitute values for xxx into the equation for the graph and work out the corresponding values for yyy. We often put these values in a table to make our work clearer. Once we have calculated the coordinates...

Connect each pair of consecutive points with a straight line. Show step Reading and interpreting line graphs The purpose of drawing a line graph (or time series) is to spot trends over a period of time. This is much easier when looking at a plotted set of data, rather than data within ...

It is often useful or necessary to find out what the gradient of a graph is. For a straight-line graph, pick two points on the graph. The gradient of the line = (change in y-coordinate)/(change in x-coordinate) . Image In this graph, the gradient = (change in y-coordinate)/(cha...

solve simultaneous linear equations using straight line graphs If an equation has two unknowns, such as 2y + x = 20, it cannot have unique solutions. Two unknowns require two equations which are solved at the sametime (simultaneously) − but even then two equations involving two unknowns do...
