Graphs are part of the KS3 Maths adventure. They might look tricky, but, like most maths stuff, once you crack them, they're a breeze.
Imagine graphs as cool pictures that tell stories with numbers. Don't stress – graphs are just a fancy way to record information. This quiz is like your map into the world of graphs, making things clearer along the way.

The paper on which a graph is drawn is often referred to as grid paper or graph paper - it has regular lines both across the page and up-and-down the page
|
All points on the graph are measured from the x axis and the y axis
|
||||||||||||||||||||||||
One axis but two axes (pronounced ack-sees)
|
You need to ensure that you never confuse the two axes and therefore it is important to remember this rhyme: 'y goes high to the sky'
|
||||||||||||||||||||||||
Y goes to the sky, x goes right to left
|
It should be noted that graphs are often drawn that show only the positive values, but this does not always mean that the negative values are unimportant
|
||||||||||||||||||||||||
The coordinates of the origin are (0, 0)
|
The y axis crosses the x at its 0 point
|
||||||||||||||||||||||||
The coordinates firstly give the position along the x axis and then the position along the y axis. To remember which number comes first, remember that x comes before y in the alphabet
|
The first quadrant is the top right and then you move from one quadrant to the next in an ANTICLOCKWISE direction
