How do i make a linear function, what is a linear function?

I have uploaded a picture so you could understand it a little more.

A linear function is when there is a table that gives numbers that represent a function, as shown in the picture.

In the Image, there is a table with a x and y column. And in both columns, there are numbers.

This is what the table looks like in the picture:

 x   y  

0    4                       The key is y = 2x + 4

1     6 <------      lets grab the number 1 in the x column and lets

2    8       multiply it by two.  Now add four to it, and we will

3    10                  have the number 6 in the y column.

4    12
