Our coordinates are (3, 2).

### Example Question #1 : How To Find The Midpoint Of A Line Segment

Point X (2, 9) and Point Y (8, 3) are endpoints on a line segment. What is the Midpoint M of that line segment?

**Possible Answers:**

**Correct answer:**

To find the midpoint of a line segment, you add together the components and divide by two ( = 5) , do the same for ( =6). The answer is (5, 6).

### Example Question #3 : How To Find The Midpoint Of A Line Segment

What is the midpoint of the points (3,12) and (9,15)?

**Possible Answers:**

**Correct answer:**

To find the midpoint we must know the midpoint formula which is

We then take the -coordinate from the first point and plug it into the formula as .

We take the -coordinate from the second point and plug it into the formula as .

We then do the same for and .

With all of the points plugged in our equation will look like this.

We then perform the necessary addition and division to get the answer of

### Example Question #6 : How To Find The Midpoint Of A Line Segment

A line is drawn from (2,4) to (8,28). What are the coordinates of its midpoint?

**Possible Answers:**

**Correct answer:**

The length to the midpoint is the difference between the two points divided by two. That number must then be added to the point:

### Example Question #7 : How To Find The Midpoint Of A Line Segment

A line segment begins at and ends at the point . What is the location of its midpoint?

**Possible Answers:**

**Correct answer:**

The difference in -values is 14 and the difference in -values is 8. The midpoint therefore differs by values of 7 and 4 from either of the endpoints.
