For this case we have the following expression:
10x + 2
There are many different ways to describe the expression.
We will name some of these ways:
1) The expression is a linear function
2) The slope of the line is positive and equal to 10.
3) The cut point of the line with the y axis is 2.
4) The domain of the function is from -inf to inf.
5) The range of the function is from -inf to inf.
