This Math quiz is called 'Algebra - Graphs 2' and it has been written by teachers to help you if you are studying the subject at middle school. Playing educational quizzes is a fabulous way to learn if you are in the 6th, 7th or 8th grade - aged 11 to 14.
It costs only $12.50 per month to play this quiz and over 3,500 others that help you with your school work. You can subscribe on the page at Join Us
In this Math quiz we look at graphs to create lines and gradients. Here we go again with graphs! No doubt you are coming to terms with the fact that graphs are VERY important in the subject of Algebra.
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!
