Question

How do you graph linear functions?

Answer 1

The easiest way (In my opinion) to graph a linear function is to enter two points, and connect them.

For example, the function:
`f(x) = 5x+3`
First you choose two `x` value. I will choose `0` and `1`. Then you enter them in the function one by one:
`f(0) = 5*0+3 = 3`
=> There is a point `(0,3)`, that's part of the function.

`f(1) = 5*1+3 = 8`
=> There is a point `(1,8)`, that's part of the function.

Since any line can be represented by two points, you can graph a linear function (line) by connecting the two points.

I hope this helped.
