Use a Table of Values to Graph the Equation y=3x

$y = 3 x$

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

$y = 3 (- 2)$

Multiply $3$ by $- 2$ .

$y = - 6$

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

$y = 3 (- 1)$

Multiply $3$ by $- 1$ .

$y = - 3$

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

$y = 3 (0)$

Solve the equation for $y$ .

Remove parentheses.

$y = 3 (0)$

Multiply $3$ by $0$ .

$y = 0$

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

$y = 3 (1)$

Solve the equation for $y$ .

Remove parentheses.

$y = 3 (1)$

Multiply $3$ by $1$ .

$y = 3$

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

$y = 3 (2)$

Solve the equation for $y$ .

Tap for more steps…

Remove parentheses.

$y = 3 (2)$

Multiply $3$ by $2$ .

$y = 6$

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

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