Introduction to linear graphs - a linear graph is just a straight line on a cartesian plane made up of xy coordinates travelling infinitely in each direction.
Introduction to linear graphs - a linear graph is just a straight line on a cartesian plane made up of xy coordinates travelling infinitely in each direction.
A pattern is formed using the set of xy coordinates which can then be written into a general rule:
A pattern is formed using the set of xy coordinates which can then be written into a general rule:
The y and x values in the equation are each pair of coordinates that can found along the line.
The y and x values in the equation are each pair of coordinates that can found along the line.
Notes:
Every x value corresponds to a y value along the line
The x intercept of a line is the x coordinate at the point where the line crosses the x axis (y = 0)
Points join together to make a straight line
Choose two points for x value and y values that are even and easy to read on the graph to find the gradient
