Step-by-step explanation:
Given that M is a positive integer, M + 1 is also a positive integer.
Since the difference between them is only 1, they cannot have a common factor above 1.
(For example if M is even, M + 1 must be odd and therefore they do not have a common factor 2 and so on)
Hence we conclude the GCF of M and M + 1 is 1.
It would be (0,-3) and (2,3). You can see that they have a bigger distance compared to the other points being compared.
Just 82 because in order for the number to be 83 it would have to be a 5 after the decimal (82.575= 83). Anything lower than a 5 after the decimal (82.375), would be 82. I hope this helps!
