Graph Using a Table of Values x-y=1

$x - y = 1$

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

$(- 2) - y = 1$

Solve the equation for $y$ .

Remove parentheses.

$- 2 - y = 1$

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

Add $2$ to both sides of the equation.

$- y = 1 + 2$

Add $1$ and $2$ .

$- y = 3$

Divide each term in $- y = 3$ by $- 1$ and simplify.

Divide each term in $- y = 3$ by $- 1$ .

$\frac{- y}{- 1} = \frac{3}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{y}{1} = \frac{3}{- 1}$

Divide $y$ by $1$ .

$y = \frac{3}{- 1}$

Simplify the right side.

Divide $3$ by $- 1$ .

$y = - 3$

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

$(- 1) - y = 1$

Solve the equation for $y$ .

Remove parentheses.

$- 1 - y = 1$

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

Add $1$ to both sides of the equation.

$- y = 1 + 1$

Add $1$ and $1$ .

$- y = 2$

Divide each term in $- y = 2$ by $- 1$ and simplify.

Divide each term in $- y = 2$ by $- 1$ .

$\frac{- y}{- 1} = \frac{2}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{y}{1} = \frac{2}{- 1}$

Divide $y$ by $1$ .

$y = \frac{2}{- 1}$

Simplify the right side.

Divide $2$ by $- 1$ .

$y = - 2$

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

$(0) - y = 1$

Solve the equation for $y$ .

Subtract $y$ from $0$ .

$- y = 1$

$y = \frac{1}{- 1}$

Simplify the right side.

Divide $1$ by $- 1$ .

$y = - 1$

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

$(1) - y = 1$

Solve the equation for $y$ .

Remove parentheses.

$1 - y = 1$

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

Subtract $1$ from both sides of the equation.

$- y = 1 - 1$

Subtract $1$ from $1$ .

$- y = 0$

$\frac{y}{1} = \frac{0}{- 1}$

Divide $y$ by $1$ .

$y = \frac{0}{- 1}$

Simplify the right side.

Divide $0$ by $- 1$ .

$y = 0$

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

$(2) - y = 1$

Solve the equation for $y$ .

Remove parentheses.

$2 - y = 1$

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

Subtract $2$ from both sides of the equation.

$- y = 1 - 2$

Subtract $2$ from $1$ .

$- y = - 1$
