I have to find the midpoint of this line segment;
P(2,8)
Q(5,8) Thanks. This question is from textbook Intermediate Algebra

Given the two points:
.
P(2,8)
Q(5,8)
.
The x-value of the midpoint of the line joining these two points is halfway between
the x-values of the two points. The two x-values are 2 and 5. Halfway between these
two values is 3.5. You can also find this by averaging the two x-values. The average
of 2 and 5 is found by adding these two values and dividing by 2. Averaging the two x
values for this problem is done this way:
.
(2 + 5)/2 = 7/2 = 3.5
.
The y-value of the midpoint of the line joining these two points is also halfway between
the y-values of the two points. The two y-values are 8 and 8. Halfway between these
two values is still 8 (since there is zero difference). You can also confirm this by
averaging the two y-values. The sum of the two y-values is 8 + 8 or 16. Divide this sum
by 2 to get the average y-value as 16/2 = 8.
.
So the midpoint of the line that connects the two given points is (3.5, 8).
.
In general, if you are given any two points and asked to find the midpoint of the line
joining them, you get the x-value of the midpoint by averaging the x-values of the two
points. And you find the y-value of the midpoint by averaging the y-values of the two
points.
.
In this problem the two points have the same y-value. This means that the line connecting
the points is a horizontal line that runs between the x-values 2 and 5. So the midpoint
is just halfway along this horizontal line. This verifies that to be on the line, the
y-value of the midpoint must be 8. And the x-value must be halfway between x= 2 and x = 5.
.
Again, in summary the midpoint of the line joining the given points is (3.5, 8).
.
Hope this explains the process of finding midpoints of lines joining two given points.
