Graph Using a Table of Values y=5x-9

$y = 5 x - 9$

Step 1

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

$y = 5 (- 2) - 9$

Step 2

Simplify $5 (- 2) - 9$ .

Multiply $5$ by $- 2$ .

$y = - 10 - 9$

Subtract $9$ from $- 10$ .

$y = - 19$

Step 3

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

$y = 5 (- 1) - 9$

Step 4

Simplify $5 (- 1) - 9$ .

Multiply $5$ by $- 1$ .

$y = - 5 - 9$

Subtract $9$ from $- 5$ .

$y = - 14$

Step 5

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

$y = 5 (0) - 9$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = 5 (0) - 9$

Simplify $5 (0) - 9$ .

Multiply $5$ by $0$ .

$y = 0 - 9$

Subtract $9$ from $0$ .

$y = - 9$

Step 7

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

$y = 5 (1) - 9$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = 5 (1) - 9$

Simplify $5 (1) - 9$ .

Multiply $5$ by $1$ .

$y = 5 - 9$

Subtract $9$ from $5$ .

$y = - 4$

Step 9

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

$y = 5 (2) - 9$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = 5 (2) - 9$

Simplify $5 (2) - 9$ .

Multiply $5$ by $2$ .

$y = 10 - 9$

Subtract $9$ from $10$ .

$y = 1$

Step 11

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

$\begin{array}{c} x & y \\ - 2 & - 19 \\ - 1 & - 14 \\ 0 & - 9 \\ 1 & - 4 \\ 2 & 1 \end{array}$
