KS3 Maths Quiz - Level 5-6 Algebra - Graphs 02 (Questions)

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!

1. The following coordinates are at either end of a line drawn on a graph: (-3, 3) and (6, 3). Where does this line appear?

KS3 Maths Quiz - Level 5-6 Algebra - Graphs 02 (Answers)
1. The following coordinates are at either end of a line drawn on a graph: (-3, 3) and (6, 3). Where does this line appear?
 [x] Above the x axis [ ] Below the x axis [ ] Along the x axis [ ] All to the left of the y axis
This is a horizontal line - note that in both sets of coordinates the second numbers are the same
2. The following coordinates are at either end of a line drawn on a graph: (-5, -3) and (-5, 8). Where does this line appear?
 [ ] To the right of the y axis [x] To the left of the y axis [ ] Along the y axis [ ] All above the x axis
This is a vertical line - note that in both sets of coordinates the first numbers are the same
3. The following coordinates are at either end of a line drawn on a graph: (0, -1) and (0, 7). Where does this line appear?
 [ ] To the right of the y axis [ ] To the left of the y axis [x] Along the y axis [ ] All above the x axis
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
4. A graph in the form of y = b is what?
 [x] A straight horizontal line [ ] A straight vertical line [ ] A left to right diagonal line [ ] A right to left diagonal line
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'
5. Describe the line y = -2
 [ ] A horizontal line running two units above the x axis [x] A horizontal line running two units below the x axis [ ] A vertical line running two units to the left of the y axis [ ] A vertical line running two units to the right of the y axis
Every coordinate on the line would have the structure of (?, -2)
6. A graph in the form of x = a is what?
 [ ] A straight horizontal line [x] A straight vertical line [ ] A left to right diagonal line [ ] A right to left diagonal line
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'
7. Describe the line x = 4
 [ ] A horizontal line running four units above the x axis [ ] A horizontal line running four units below the x axis [ ] A vertical line running four units to the left of the y axis [x] A vertical line running four units to the right of the y axis
Every coordinate on the line would have the structure of (4, ?)
8. The graph y = x has a line that goes from where to where?
