Graph Using a Table of Values y=-9x

$y = - 9 x$

Step 1

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

$y = - 9 \cdot - 2$

Step 2

Solve the equation for $y$ .

Remove parentheses.

$y = - 9 \cdot - 2$

Multiply $- 9$ by $- 2$ .

$y = 18$

Step 3

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

$y = - 9 \cdot - 1$

Step 4

Solve the equation for $y$ .

Remove parentheses.

$y = - 9 \cdot - 1$

Multiply $- 9$ by $- 1$ .

$y = 9$

Step 5

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

$y = - 9 \cdot 0$

Step 6

Solve the equation for $y$ .

Remove parentheses.

$y = - 9 \cdot 0$

Multiply $- 9$ by $0$ .

$y = 0$

Step 7

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

$y = - 9 \cdot 1$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$y = - 9 \cdot 1$

Multiply $- 9$ by $1$ .

$y = - 9$

Step 9

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

$y = - 9 \cdot 2$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$y = - 9 \cdot 2$

Multiply $- 9$ by $2$ .

$y = - 18$

Step 11

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

$\begin{array}{c} x & y \\ - 2 & 18 \\ - 1 & 9 \\ 0 & 0 \\ 1 & - 9 \\ 2 & - 18 \end{array}$
