Graph Using a Table of Values y=4x-2

$y = 4 x - 2$

Step 1

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

$y = 4 (- 2) - 2$

Step 2

Simplify $4 (- 2) - 2$ .

Multiply $4$ by $- 2$ .

$y = - 8 - 2$

Subtract $2$ from $- 8$ .

$y = - 10$

Step 3

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

$y = 4 (- 1) - 2$

Step 4

Simplify $4 (- 1) - 2$ .

Multiply $4$ by $- 1$ .

$y = - 4 - 2$

Subtract $2$ from $- 4$ .

$y = - 6$

Step 5

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

$y = 4 (0) - 2$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = 4 (0) - 2$

Simplify $4 (0) - 2$ .

Multiply $4$ by $0$ .

$y = 0 - 2$

Subtract $2$ from $0$ .

$y = - 2$

Step 7

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

$y = 4 (1) - 2$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = 4 (1) - 2$

Simplify $4 (1) - 2$ .

Multiply $4$ by $1$ .

$y = 4 - 2$

Subtract $2$ from $4$ .

$y = 2$

Step 9

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

$y = 4 (2) - 2$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = 4 (2) - 2$

Simplify $4 (2) - 2$ .

Multiply $4$ by $2$ .

$y = 8 - 2$

Subtract $2$ from $8$ .

$y = 6$

Step 11

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

$\begin{array}{c} x & y \\ - 2 & - 10 \\ - 1 & - 6 \\ 0 & - 2 \\ 1 & 2 \\ 2 & 6 \end{array}$
