$y$ .

y = 3 (- 2)

$y = 3 (- 2)$

Step 2

Multiply

3

$3$ by

- 2

$- 2$ .

y = - 6

$y = - 6$

Step 3

Substitute

- 1

$- 1$ for

x

$x$ and find the result for

y

$y$ .

y = 3 (- 1)

$y = 3 (- 1)$

Step 4

Multiply

3

$3$ by

- 1

$- 1$ .

y = - 3

$y = - 3$

Step 5

Substitute

0

$0$ for

x

$x$ and find the result for

y

$y$ .

y = 3 (0)

$y = 3 (0)$

Step 6

Step 10.1

Remove parentheses.

y = 3 (2)

$y = 3 (2)$

Step 10.2

Multiply

3

$3$ by

2

$2$ .

y = 6

$y = 6$

y = 6

$y = 6$

Step 11

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

\begin{array}{c} x & y \\ - 2 & - 6 \\ - 1 & - 3 \\ 0 & 0 \\ 1 & 3 \\ 2 & 6 \end{array}

$\begin{array}{c} x & y \\ - 2 & - 6 \\ - 1 & - 3 \\ 0 & 0 \\ 1 & 3 \\ 2 & 6 \end{array}$

Step 12

y = 3 x

$y = 3 x$
