Match the graphs with their equations or descriptions. A self-marking, drag-and-drop mathematical exercise.
This is Level 2 (Linear and quadratic graphs and equations). Match the graphs with the corresponding equations.
\(y = x^2 − 3\)
\(y = 3 + 2x\)
\(y = (x + 3)^2\)
\(y = - x\)
\(y = -3\)
\(y = \frac14 x + 2\)
\(x = 2\)
\(y = 3 − 2x\)
\(y = (2 − x)^2\)
\(y = \frac13 x^2\)
\(y = 5 − x^2\)
\(y = 5 − 3x\)
The diagrams were created in Autograph.
Gradient - A pre-requisite for doing the graph exercises is being able to calculate the gradient of a line.
Level 1 - Linear graphs and equations
Level 2 - Linear and quadratic graphs and equations
Level 3 - Mixed polynomials
Level 4 - Quadratics in the form \(ax^2 + bx + c\) given information about the coefficients
Exam Style questions are in the style of GCSE or IB/A-level exam paper questions and worked solutions are available for Transum subscribers.
More on this topic including lesson Starters, visual aids and investigations.
For straight line graphs arrange the equation in the form \(y = mx + c\) where \(m\) represents the gradient of the line and \(c\) the y-intercept.
Maybe this video will remind you of some of the techniques for recognising graphs.

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?
Comment recorded on the 3 October 'Starter of the Day' page by S Mirza, Park High School, Colne:
"Very good starters, help pupils settle very well in maths classroom."
Comment recorded on the 28 May 'Starter of the Day' page by L Smith, Colwyn Bay:
"An absolutely brilliant resource. Only recently been discovered but is used daily with all my classes. It is particularly useful when things can be saved for further use. Thank you!"

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths main page links to more activities designed for students in upper Secondary/High school.
If you found this activity useful don't forget to record it in your scheme of work or learning management system. The short URL, ready to be copied and pasted, is as follows:
