Graph Using a Table of Values y=4x

$y = 4 x$

Step 1

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

$y = 4 (- 2)$

Step 2

Multiply $4$ by $- 2$ .

$y = - 8$

Step 3

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

$y = 4 (- 1)$

Step 4

Multiply $4$ by $- 1$ .

$y = - 4$

Step 5

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

$y = 4 (0)$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = 4 (0)$

Multiply $4$ by $0$ .

$y = 0$

Step 7

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

$y = 4 (1)$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = 4 (1)$

Multiply $4$ by $1$ .

$y = 4$

Step 9

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

$y = 4 (2)$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = 4 (2)$

Multiply $4$ by $2$ .

$y = 8$

Step 11

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

$\begin{array}{c} x & y \\ - 2 & - 8 \\ - 1 & - 4 \\ 0 & 0 \\ 1 & 4 \\ 2 & 8 \end{array}$
