Answer: (4, -1)</h3>
Reason:
When rotating a point 180 degrees around the origin, you use the rule

We flip the sign of each coordinate from positive to negative or vice versa.
The point X is at the location (-4, 1). Rotating this 180 degrees will get us to X'(4, -1)
For 645 and 738:
For these numbers we have that the difference between both is:
738 - 645 = 93
For 645 and 649:
For these numbers we have that the difference between both is:
649 - 645 = 4
Therefore, comparing the first two numbers of the second two numbers is different because the difference between the first two numbers is much larger.
Answer:
The difference between the first two numbers is much greater than the difference between the second two numbers.
