Linear Graph (Chapter 12)
posted by Mr Johari
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 y-intercept
Form the general linear equation ie. y=mx+c, where m is the gradient and c is the y-intercept.
Given a linear line, find the equation of the line.
