Graph Using a Table of Values x+2y=6

$x + 2 y = 6$

Step 1

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

$(- 2) + 2 y = 6$

Step 2

Solve the equation for $y$ .

Remove parentheses.

$- 2 + 2 y = 6$

Move all terms not containing $y$ to the right side of the equation.

Add $2$ to both sides of the equation.

$2 y = 6 + 2$

Add $6$ and $2$ .

$2 y = 8$

Divide each term in $2 y = 8$ by $2$ and simplify.

Divide each term in $2 y = 8$ by $2$ .

$\frac{2 y}{2} = \frac{8}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{8}{2}$

Divide $y$ by $1$ .

$y = \frac{8}{2}$

Simplify the right side.

Divide $8$ by $2$ .

$y = 4$

Step 3

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

$(- 1) + 2 y = 6$

Step 4

Solve the equation for $y$ .

Remove parentheses.

$- 1 + 2 y = 6$

Move all terms not containing $y$ to the right side of the equation.

Add $1$ to both sides of the equation.

$2 y = 6 + 1$

Add $6$ and $1$ .

$2 y = 7$

Divide each term in $2 y = 7$ by $2$ and simplify.

Divide each term in $2 y = 7$ by $2$ .

$\frac{2 y}{2} = \frac{7}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{7}{2}$

Divide $y$ by $1$ .

$y = \frac{7}{2}$

Step 5

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

$(0) + 2 y = 6$

Step 6

Solve the equation for $y$ .

Add $0$ and $2 y$ .

$2 y = 6$

Divide each term in $2 y = 6$ by $2$ and simplify.

Divide each term in $2 y = 6$ by $2$ .

$\frac{2 y}{2} = \frac{6}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{6}{2}$

Divide $y$ by $1$ .

$y = \frac{6}{2}$

Simplify the right side.

Divide $6$ by $2$ .

$y = 3$

Step 7

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

$(1) + 2 y = 6$

Step 8

Solve the equation for $y$ .

Remove parentheses.

$1 + 2 y = 6$

Move all terms not containing $y$ to the right side of the equation.

Subtract $1$ from both sides of the equation.

$2 y = 6 - 1$

Subtract $1$ from $6$ .

$2 y = 5$

Divide each term in $2 y = 5$ by $2$ and simplify.

Divide each term in $2 y = 5$ by $2$ .

$\frac{2 y}{2} = \frac{5}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{5}{2}$

Divide $y$ by $1$ .

$y = \frac{5}{2}$

Step 9

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

$(2) + 2 y = 6$

Step 10

Solve the equation for $y$ .

Remove parentheses.

$2 + 2 y = 6$

Move all terms not containing $y$ to the right side of the equation.

Subtract $2$ from both sides of the equation.

$2 y = 6 - 2$

Subtract $2$ from $6$ .

$2 y = 4$

Divide each term in $2 y = 4$ by $2$ and simplify.

Divide each term in $2 y = 4$ by $2$ .

$\frac{2 y}{2} = \frac{4}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{4}{2}$

Divide $y$ by $1$ .

$y = \frac{4}{2}$

Simplify the right side.

Divide $4$ by $2$ .

$y = 2$

Step 11

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

$\begin{array}{c} x & y \\ - 2 & 4 \\ - 1 & \frac{7}{2} \\ 0 & 3 \\ 1 & \frac{5}{2} \\ 2 & 2 \end{array}$
