Step-by-step explanation:

Where Z is set of integer.
Answer:
-3/2, -1
Step-by-step explanation:
Each coordinate contains one
value and one
value,
.
If we work out the midpoint of each of these individually, it makes it much easier to find the midpoint of the line.
Let's take the
values first. Our first
value is -4 and our second
value is 1. Imagine the integers between -4 and 1 laid out in a sequence:

If you take the middle value of this sequence, you get the midpoint of the
values.
In this case, the middle is between values -2 and -1, leaving us with a midpoint of -1.5. This as a fraction is
.
Now let's look at the
values. Our first
value is 2 and our second
value is -4. Again, let's imagine those numbers laid out in a sequence:

Here, the middle of these values is -1, and this is the midpoint of the
values.
So if we put these two values in a coordinate, we get the midpoint of the line.
In this case, we get
.
If x is 2, you substitute all the x in the expression for the number 2:
2 - 2 - 1 + 12
-1 + 12
11
