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 ...

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 ...

It is also possible to have a conversion graph to switch between units that are not directly proportional. For example, temperature can be measured in degrees Centigrade (°C) and degrees Fahrenheit ...
