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 .
