Graph Using a Table of Values y=12x-7

$y = 12 x - 7$

Step 1

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

$y = 12 (- 2) - 7$

Step 2

Simplify $12 (- 2) - 7$ .

Multiply $12$ by $- 2$ .

$y = - 24 - 7$

Subtract $7$ from $- 24$ .

$y = - 31$

Step 3

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

$y = 12 (- 1) - 7$

Step 4

Simplify $12 (- 1) - 7$ .

Multiply $12$ by $- 1$ .

$y = - 12 - 7$

Subtract $7$ from $- 12$ .

$y = - 19$

Step 5

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

$y = 12 (0) - 7$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = 12 (0) - 7$

Simplify $12 (0) - 7$ .

Multiply $12$ by $0$ .

$y = 0 - 7$

Subtract $7$ from $0$ .

$y = - 7$

Step 7

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

$y = 12 (1) - 7$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = 12 (1) - 7$

Simplify $12 (1) - 7$ .

Multiply $12$ by $1$ .

$y = 12 - 7$

Subtract $7$ from $12$ .

$y = 5$

Step 9

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

$y = 12 (2) - 7$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = 12 (2) - 7$

Simplify $12 (2) - 7$ .

Multiply $12$ by $2$ .

$y = 24 - 7$

Subtract $7$ from $24$ .

$y = 17$

Step 11

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

$\begin{array}{c} x & y \\ - 2 & - 31 \\ - 1 & - 19 \\ 0 & - 7 \\ 1 & 5 \\ 2 & 17 \end{array}$
