Find Three Ordered Pair Solutions y=1/2x-9

$y = \frac{1}{2} x - 9$

Step 1

Combine $\frac{1}{2}$ and $x$ .

$y = \frac{x}{2} - 9$

Step 2

Choose any value for $x$ that is in the domain to plug into the equation.

Step 3

Choose $0$ to substitute in for $x$ to find the ordered pair.

Remove parentheses.

$y = \frac{0}{2} - 9$

Simplify $\frac{0}{2} - 9$ .

Divide $0$ by $2$ .

$y = 0 - 9$

Subtract $9$ from $0$ .

$y = - 9$

Use the $x$ and $y$ values to form the ordered pair.

$(0, - 9)$

Step 4

Choose $1$ to substitute in for $x$ to find the ordered pair.

Remove parentheses.

$y = \frac{1}{2} - 9$

Simplify $\frac{1}{2} - 9$ .

To write $- 9$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$y = \frac{1}{2} - 9 \cdot \frac{2}{2}$

Combine $- 9$ and $\frac{2}{2}$ .

$y = \frac{1}{2} + \frac{- 9 \cdot 2}{2}$

Combine the numerators over the common denominator.

$y = \frac{1 - 9 \cdot 2}{2}$

Simplify the numerator.

Multiply $- 9$ by $2$ .

$y = \frac{1 - 18}{2}$

Subtract $18$ from $1$ .

$y = \frac{- 17}{2}$

Move the negative in front of the fraction.

$y = - \frac{17}{2}$

Use the $x$ and $y$ values to form the ordered pair.

$(1, - \frac{17}{2})$

Step 5

Choose $2$ to substitute in for $x$ to find the ordered pair.

Remove parentheses.

$y = \frac{2}{2} - 9$

Simplify $\frac{2}{2} - 9$ .

Divide $2$ by $2$ .

$y = 1 - 9$

Subtract $9$ from $1$ .

$y = - 8$

Use the $x$ and $y$ values to form the ordered pair.

$(2, - 8)$

Step 6

These are three possible solutions to the equation.

$(0, - 9), (1, - \frac{17}{2}), (2, - 8)$

Step 7
