Find Three Ordered Pair Solutions y=-4x+20

$y = - 4 x + 20$

Step 1

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

Step 2

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

Remove parentheses.

$y = - 4 \cdot 0 + 20$

Simplify $- 4 \cdot 0 + 20$ .

Multiply $- 4$ by $0$ .

$y = 0 + 20$

Add $0$ and $20$ .

$y = 20$

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

$(0, 20)$

Step 3

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

Remove parentheses.

$y = - 4 \cdot 1 + 20$

Simplify $- 4 \cdot 1 + 20$ .

Multiply $- 4$ by $1$ .

$y = - 4 + 20$

Add $- 4$ and $20$ .

$y = 16$

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

$(1, 16)$

Step 4

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

Remove parentheses.

$y = - 4 \cdot 2 + 20$

Simplify $- 4 \cdot 2 + 20$ .

Multiply $- 4$ by $2$ .

$y = - 8 + 20$

Add $- 8$ and $20$ .

$y = 12$

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

$(2, 12)$

Step 5

These are three possible solutions to the equation.

$(0, 20), (1, 16), (2, 12)$
