Step 1.1.1

Raise $8$ to the power of $2$ .

$f (x) = - 1 \cdot 64 + 6 x + 5$

Step 1.1.2

Multiply $- 1$ by $64$ .

$f (x) = - 64 + 6 x + 5$

Step 1.2

Add $- 64$ and $5$ .

$f (x) = 6 x - 59$

Step 2

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 $f (x) = 6 x - 59$ is $1$ , which makes the function a linear function.

$f (x) = 6 x - 59$ is a linear function
