(Additional Practice) Linear Graphs Plotting

Some of you have expressed that you want to have more practice on Graph Plotting (for the topic: Functions and Linear Graphs), and you are not able to find such practice questions in the Exam Prep Booklet.

A handout has been created with 4 more questions.
You may use this as a practice.
They are available in the GoogleSite, under the class page:

Scroll down to the folder: 
 Chap 08 Functions and Linear Graphs

Then look for the file:

Revision (1) Ratio, Rate & Speed (2) Data Handling

Please note that 2 Quizzes (from Ace Learning) have been assigned.
They serve as revision exercise for the upcoming level test.

You are strongly encouraged to revise your work (Notes) before attempting the questions.
Calculator is allowed. 


You could re-attempt the Quiz (if necessary) once after the first round. 
Your score will be consolidated and it will contribute to group point.
To qualify for group point, you have to attempt the quizzes before the Level Test.

Graph Mole

Read the "Introduction" to find out the context and the "how-to" of the game before "playing the game" to challenge yourself!
It's a "combination" of knowledge and speed! Enjoy!
