There is no -intercept. I must assume without any other information, that the given points are all of the elements of the set that comprise your function. In other words:



The -intercept of any function is the ordered pair(s) that is an element of the set that enumerates the function where the -coordinate is equal to zero.

The -intercept is the point where the -coordinate is zero.

The value of the function at any point in its domain is -4. So the indicated sum is two instances of the function evaluated at two different values from the domain of the function, each of which evaluates to -4, added together. I'll let you ponder the actual arithmetic involved. Here is a point of view that may eliminate some of the confusion, at least as far as this part of the question is concerned: Stop thinking about ordered pairs as , rather think of them as
