What order does not represent a function {(5, -1),(-6, -7), (-5, - 7), (9,6)} {(8,-1), (-4,-1), (-6,5), (4, -2)} {(8,6),(-1,2), (8, -8),(1,9)}
{(-1,1), (7,-2), (-7, -3), (0, –3)}

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
