Introduction to Linear Inequalities
 Suppose you have a gift card for $100 to an electronics store and want to spend it on CDs and DVDs. You want a specialedition DVD that costs $24.99, and the CDs you want are all on sale for $11.99 each. Assuming that you use only the gift card and you are going to buy the DVD, what is the maximum number of CDs you can buy?
 You know you can buy at least one CD. What about two CDs? It can be time consuming to keep checking.
 Suggest ways to solve this problem.

Linear Graph (Chapter 12)
posted by Mr Johari
source: http://www.math.com/school
This is a supplementary note that focuses on plotting of a linear equation:
Part 1: Graphing Linear Equation
Method 1: Given linear equation, plot the graph.
Technique: Using plotting points and coordinates. (i.e. identify any points for x and find corresponding values of y for plotting)
Method 2: Given linear equation, plot the graph.
Technique: Using gradient and yintercept
Form the general linear equation ie. y=mx+c, where m is the gradient and c is the yintercept.
Given a linear line, find the equation of the line.
