# Find Three Ordered Pair Solutions 4x-y=9 4x-y=9
Solve the equation for y.
Subtract 4x from both sides of the equation.
-y=9-4x
Multiply each term in -y=9-4x by -1
Multiply each term in -y=9-4x by -1.
(-y)⋅-1=9⋅-1+(-4x)⋅-1
Multiply (-y)⋅-1.
Multiply -1 by -1.
1y=9⋅-1+(-4x)⋅-1
Multiply y by 1.
y=9⋅-1+(-4x)⋅-1
y=9⋅-1+(-4x)⋅-1
Simplify each term.
Multiply 9 by -1.
y=-9+(-4x)⋅-1
Multiply -1 by -4.
y=-9+4x
y=-9+4x
y=-9+4x
y=-9+4x
Choose any value for x that is in the domain to plug into the equation.
Choose 0 to substitute in for x to find the ordered pair.
Remove parentheses.
y=-9+4(0)
Simplify -9+4(0).
Multiply 4 by 0.
y=-9+0
Add -9 and 0.
y=-9
y=-9
Use the x and y values to form the ordered pair.
(0,-9)
(0,-9)
Choose 1 to substitute in for x to find the ordered pair.
Remove parentheses.
y=-9+4(1)
Simplify -9+4(1).
Multiply 4 by 1.
y=-9+4
Add -9 and 4.
y=-5
y=-5
Use the x and y values to form the ordered pair.
(1,-5)
(1,-5)
Choose 2 to substitute in for x to find the ordered pair.
Remove parentheses.
y=-9+4(2)
Simplify -9+4(2).
Multiply 4 by 2.
y=-9+8
Add -9 and 8.
y=-1
y=-1
Use the x and y values to form the ordered pair.
(2,-1)
(2,-1)
These are three possible solutions to the equation.
(0,-9),(1,-5),(2,-1)
