Graphs are something you need to familiarise yourself with in KS3 Maths. They may seem complicated but, as with most things, graphs are simple once you understand them. But what have graphs got to do with algebra? Well, most shapes can be drawn on a graph by using formulae to describe their coordinates.
A graph is a type of chart or diagram used to represent information. To draw graphs you need to be able to place points accurately on a grid before joining them up. The position of a point is described by its coordinates, the distances from the x and y axes. The axes intersect at their 0 points and proceed into minus coordinates as well as positive ones.
Have a go at this quiz to familiarise yourself with graphs. As ever, take your time and study each question carefully before you choose your answer. And don't forget to read the helpful comments which follow each question. These will help to explain any questions you didn't understand. Good luck!
