Find Three Ordered Pair Solutions f(x)=7-3x

$f (x) = 7 - 3 x$

Step 1

Write $f (x) = 7 - 3 x$ as an equation.

$y = 7 - 3 x$

Step 2

Reorder $7$ and $- 3 x$ .

$y = - 3 x + 7$

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.

Remove parentheses.

$y = - 3 \cdot 0 + 7$

Simplify $- 3 \cdot 0 + 7$ .

Multiply $- 3$ by $0$ .

$y = 0 + 7$

Add $0$ and $7$ .

$y = 7$

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

$(0, 7)$

Step 5

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

Remove parentheses.

$y = - 3 \cdot 1 + 7$

Simplify $- 3 \cdot 1 + 7$ .

Multiply $- 3$ by $1$ .

$y = - 3 + 7$

Add $- 3$ and $7$ .

$y = 4$

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

$(1, 4)$

Step 6

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

Remove parentheses.

$y = - 3 \cdot 2 + 7$

Simplify $- 3 \cdot 2 + 7$ .

Multiply $- 3$ by $2$ .

$y = - 6 + 7$

Add $- 6$ and $7$ .

$y = 1$

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

$(2, 1)$

Step 7

These are three possible solutions to the equation.

$(0, 7), (1, 4), (2, 1)$

Step 8
