Learn the difference between lines with the same slope and those with an opposite reciprocal slope. This quick guide breaks ...

Remember that to find the equation of a straight line you need to know its gradient and a point on the line. In some instances you are told the value of the gradient, however there are times where you ...

In this video series I show you how to determine a line that is parallel or perpendicular to another line through a point.

All straight line graphs have an equation that can be written in the form 𝑦 equals 𝑚𝑥 add 𝑐, where 𝑚, the coefficient of the 𝑥 term, is the gradient or slope of the line. The constant, 𝑐, is ...
