Question 9460: In the notation (-4,8) what is the -4 called? What is the 8 called?
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! (-4, 8) actually has several meanings in math. The most common meaning, when dealing with two variables (like a graph with x and y), the first number is x and the second number is y.
There are other meanings such as, when there is only one variable involved, a method of describing an interval of numbers on the numberline. This is called "interval notation," and (-4, 8) in this case means all values of x on the numberline between -4 and 8, but not including either endpoint.
How do you know the difference? ANSWER: The CONTEXT of the problem.
You probably had the first meaning in mind, right?
