Determine if an Ordered Pair is a Solution:

- An ordered pair is of the form: (x, y)
- Plug in the first component (leftmost value) for x in the equation
- Plug in the second component (rightmost value) for y in the equation
- Evaluate and determine if the equation results in a true statement
- Left and right sides must be the same value

Complete an Ordered Pair:

- Plug in for the known variable
- Solve for the unknown variable
- Check the ordered pair, determine if the equation results in a true statement
- Left and right sides must be the same value
