In this week we learned about linear relations and how to use them in a t-chart.  You can be given a set of numbers such as 4,8,12.  We learned to start by establishing to say start at 4 increase by 4 each time.  You put these numbers into a t-chart divided into X and Y,  the numbers you are given eg; 4,8,12 go in the Y column.  In the X column you labell it 1,2,3.  To find the rule you start by figuring out the change in the numbers in the Y column, in this case they increase by 4.  If we multiply 1,2,3 by 4 we get the numbers in the Y column.
