By now you'll know that graphs are something you need to get to grips with in KS3 Maths. There is so much to them: representing shapes, recording information, reflections, rotations and much more besides. Algebra is also associated with graphs, what with x and y values and formulas for describing shapes. In this particular quiz we'll focus on using graphs to create lines and gradients.
So, here we go again with graphs! You'll be tested on placing coordinates, describing the position of lines, describing different types of lines and your knowledge of terms used. It all sounds very complicated, I'm sure. But, with a little practise, the world of graphs will soon become a breeze!
In the quiz that follows, you'll be asked ten questions all about graphs. Take your time and don't rush! Read each question carefully and make sure you understand them before choosing your answers. So, if you're ready, begin the quiz. Let's see how well you do!














This is a horizontal line  note that in both sets of coordinates the second numbers are the same

This is a vertical line  note that in both sets of coordinates the first numbers are the same


Both sets of coordinates show the x axis figure of 0 and this means that the line must run up and down the y axis

Listen up because this is important....... In the above equation (y = b) the b part of the equation really means anything/something. What you might be asked is something like 'draw the graph y = 2'


Every coordinate on the line would have the structure of (?, 2)

In the above equation (x = a) the a part of the equation really means anything/something. What you might be asked is something like 'draw the graph x = 4'


Every coordinate on the line would have the structure of (4, ?)

Think of it this way: if y = 4 then x = 4, if y = 4 then x = 4. In other words, whatever the first number in the coordinates, the second number will always be the same


Think of it this way: if y = 4 then x = 4, if y = 4 then x = 4. In other words, whatever the first number in the coordinates, the second number will always be the same BUT with the opposite sign

After all that heavy stuff we thought you deserved an easy question!
