Given expression is
.
where 
Now we have to simplify this and find the next step so that negative exponent gets eliminated.
We know that when negative exponent changes sign, then it moves from numerator to denominator or from denominator to numerator as shown in the formula:

or
n has negative exponent in denominator so it will move to numerator and we get:

or 
Hence final answer is
.
Using an ordered pair is a way of graphing a linear equation on a coordinate plane.
{(-1, 2), (0, 1), (1, 2), (4, 5)}.
