Answer:

x = 7; NO

Step-by-step explanation:

Notice that the x-coordinate remains the same, 7, for both points, whereas the y-coordinate changes.  Thus, the line through these two points is a vertical one:  x = 7.  No, this is not a function, since one x value (7) has more than one y values associated with it.
