Review: Coordinates
Remember that the first number is the -coordinate and the second number is the -coordinate.
Along first, then up or down.

Example 1
(a) Plot the points (1, 2) (2,3) (3,4) (4,5) and (5,6).(b) Draw a straight line through these points.

Table of values
Given the equation of a straight line, I can complete a table of values.
From a table of values, I can draw a straight line.

Table of values
Complete the table below for
To do this, replace different values of into the equation
-2 -1 0 1 2

Plot the points (-2, -3) (-1, -1) (0, 1) (1, 3) (2, 5)
A straight line can be drawn through these points

Scatter graph
Given a set of data, I can plot points on a scatter graph.
I can draw a line of best fit.

Scatter graphs
Scatter graphs are used to represent and compare two sets of data.By looking at a scatter diagram it is possible to say whether there is any connection (correlation) between the two sets of data.

Line of Best Fit
When there is a correlation between sets of data on a scatter graph, it is possible to draw a line of best fit.
When drawing a line of best fit the aim is to keep the distance of all the points from the line to a minimum.
Sometimes it is helpful to try to keep the number of points above the line as the same as the number of points below the line.
