Find Three Ordered Pair Solutions

$f (x) = 3 x + 9 - 1$

Step 1

Write $f (x) = 3 x + 9 - 1$ as an equation.

$y = 3 x + 9 - 1$

Step 2

Subtract $1$ from $9$ .

$y = 3 x + 8$

Step 3

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

Step 4

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

Step 4.2.1

Multiply $3$ by $0$ .

$y = 0 + 8$

Step 4.2.2

Add $0$ and $8$ .

$y = 8$

Step 4.3

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

$(0, 8)$

Step 5

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

Step 5.1

Remove parentheses.

$y = 3 (1) + 8$

Step 5.2

Simplify $3 (1) + 8$ .

Step 5.2.1

Multiply $3$ by $1$ .

$y = 3 + 8$

Step 5.2.2

Add $3$ and $8$ .

$y = 11$

Step 5.3

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

$(1, 11)$

Step 6

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

Step 6.1

Remove parentheses.

$y = 3 (2) + 8$

Step 6.2

Simplify $3 (2) + 8$ .

Tap for more steps...

Step 6.2.1

Multiply $3$ by $2$ .

$y = 6 + 8$

Step 6.2.2

Add $6$ and $8$ .

$y = 14$

Step 6.3

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

$(2, 14)$

Step 7

These are three possible solutions to the equation.

$(0, 8), (1, 11), (2, 14)$
