Answer: It is a linear equation.
If you look at the values on the left, the x-values, you can see that they are neatly lined up for us and they are increasing by 1.
Now, look at the y-values, they are increasing by adding 1/2.
When you have a constant increase of a value by addition or subtraction, it will create a linear pattern. You can also graph the equation to see the linear pattern.
