In this video we are going to look at how to find the equation of a straight line that passes through two given points (coordinates). You should already know that a straight line follows the y=mx+c format, where 'm' is the gradient and...

Learn about graphs. In this second part introductory video we will look at the equation of horizontal lines and vertical lines. We will also have a quick look at two important diagonal lines. Vertical lines on a graph all have the same...

Learn about graphs. In this third part introductory video we will look at the parallel and perpendicular lines.



Both parallel and perpendicular lines are found everywhere; just think of a

car park.

Parallel...

In this video, the teacher explains how to graph linear equations using a table of values. The lesson covers the basics of linear equations, how to identify solutions, and how to graph using a coordinate plane. The teacher also covers...
