Answer:
Its b
Step-by-step explanation:
I did the unit test
It is called a constant.
Remember a "variable" means that the value of that term can change depending on the value of the "x" or "y". Since (in this case), -6 does not have a variable attached, it will not change, it will remain CONSTANT.
And there is more information needed
With negatives included, no.
You can add a negative with a positive and get a lesser number than you would when subtracting, only if you subtract the negative from the positive, making it become addition.
1 + (-1) = 0, while 1 - (-1) = 2. Some more examples are 3 and -8, 4 and -1.
Hope this helps! :)
