$f (x) = 10 x + 5$

Step 1

The word linear is used for a straight line. A linear function is a function of a straight line, which means that the degree of a linear function must be $0$ or $1$ . In this case, The degree of $f (x) = 10 x + 5$ is $1$ , which makes the function a linear function.

$f (x) = 10 x + 5$ is a linear function
