Graph Using a Table of Values f(x)=-x

$f (x) = - x$

Step 1

Substitute $- 2$ for $x$ and find the result for $y$ .

$y = - (- 2)$

Step 2

Multiply $- 1$ by $- 2$ .

$y = 2$

Step 3

Substitute $- 1$ for $x$ and find the result for $y$ .

$y = - (- 1)$

Step 4

Multiply $- 1$ by $- 1$ .

$y = 1$

Step 5

Substitute $0$ for $x$ and find the result for $y$ .

$y = - (0)$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = - (0)$

Multiply $- 1$ by $0$ .

$y = 0$

Step 7

Substitute $1$ for $x$ and find the result for $y$ .

$y = - (1)$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = - (1)$

Multiply $- 1$ by $1$ .

$y = - 1$

Step 9

Substitute $2$ for $x$ and find the result for $y$ .

$y = - (2)$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = - (2)$

Multiply $- 1$ by $2$ .

$y = - 2$

Step 11

This is a table of possible values to use when graphing the equation.

$\begin{array}{c} x & y \\ - 2 & 2 \\ - 1 & 1 \\ 0 & 0 \\ 1 & - 1 \\ 2 & - 2 \end{array}$
