 The y-axis runs vertically (up and down). Remember: 'y goes high to the sky'.

# Level 3-4 Algebra - Graphs Introduction

Graphs are something you need to get to grips with in KS3 Maths. They may seem complicated but, as with most things in maths, graphs are simple once you understand them.

A graph is a type of chart or diagram used to represent information. Very often maths students are afraid of graphs but there is no need to be. Think of graphs as a diagram or drawing that records data. This quiz will help to introduce you to graphs and, hopefully, clarify some things along the way.

We have five algebra quizzes on the subject of graphs so you'll be getting plenty of practise. If the idea of graphs does worry you then you're in the right place. Play this first introduction quiz and your fears will disappear!

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!

1.
A graph is normally drawn on a what?
Grid
Grod
Grud
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
2.
To start drawing a graph you first need to put two lines on the paper that show units of measurement. What is the name given to one of these lines?
Axis
Axle
Axon
Axura
All points on the graph are measured from the x axis and the y axis
3.
What is the plural of axis?
Axes
Axii
Axisis
Azisisisisisis
One axis but two axes (pronounced ack-sees)
4.
Which way on the page does the y axis go?
Diagonal left to right
Diagonal right to left
Horizontally - left to right
Vertically - up and down
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'
5.
The axis that goes horizontally left to right is called what?
The a axis
The b axis
The x axis
The z axis
Y goes to the sky, x goes right to left
6.
Do axes have negative values as well as positive values?
No, never
Yes, always
Only in the northern hemisphere
Sometimes
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
7.
What is the name given to the point where the x and y axes intersect?
Intersection
Mid point
Origin
Starting point
The coordinates of the origin are (0, 0)
8.
On the x axis, where are the negative figures relative to the y axis?
Above the y axis
Below the y axis
To the left of the y axis
To the right of the y axis
The y axis crosses the x at its 0 point
9.
What is the term used to define the exact position of a point on a graph?
Coordinate
Marker
Pin
Pointer
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
10.
There is only one quadrant on a graph that contains coordinates that have only positive figures in them. Which quadrant is it?
1 (top right)
2 (top left)
3 (bottom left)
4 (bottom right)
The first quadrant is the top right and then you move from one quadrant to the next in an ANTICLOCKWISE direction
