Different types of graphs and charts are needed to present results from experiments. Graphs and charts need to be drawn and labelled correctly. Use patterns in the data to reach a conclusion in an ...

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 - x\) (which can be re-written as \(y = ...

In this video we will learn about the plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of linear equations on the graph paper ...
