Linear graphs are commonly used when converting between different units of measurement. For example, swapping between temperatures in degrees Celsius (°C) and degrees Fahrenheit (°F), exchanging ...

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 ...

In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a line is calculated by dividing the difference in ...
