The second answer is correct because in order for the ordered pairs to represent a function, there can only be 1 y value for every x value. The second option has 2 different y values for x = 3 so it is not a function.
The answer is the second option.
1 fin = 8 grams
4 fins = 4 x 8 = 24 grams total
You multiply 8 times 5 then add 3. So it's 43/8
-2(10)+-3(-6)
It would be -2
