### Example Question #1 : Coordinate Geometry

What is the midpoint between and ?

**Possible Answers:**

**Correct answer:**

The midpoint is given by taking the mean, or average, of the and coordinates separately.

Let and

So the midpoint formula becomes and

So the midpoint is

### Example Question #2 : Coordinate Geometry

What is the midpoint of a line segment connecting the points and

**Possible Answers:**

**Correct answer:**

Use the midpoint formula:

### Example Question #3 : Coordinate Geometry

Given two points and and a line segment that connects the two.

What is the midpoint of the line segment? Addtionally, what is the length of the line segment?

**Possible Answers:**

Midpoint:

Length:

Midpoint:

The midpoint formula is as follows:

This makes sense; it is as simple as the average of the and components of each point.

For this problem, .

So the midpoint is

The distance formula is as follows:

The order you put the first and second components of each point does NOT matter, when a positive or negative number is squared, it will always come out positive.

So the distance is

### Example Question #1 : Coordinate Geometry

Find the midpoint of a line segment going from to .

**Possible Answers:**

**Correct answer:**

To find the midpoint of a line segment, you must find the mean of the x values and the mean of the y values.

Our x values are and to find their mean, we do .

Our y values are and , so our mean is . Therefore, our midpoint must be .

### Example Question #1 : Coordinate Geometry

Find the coordinate of the midpoint of the line segment connecting the pair of points

and .

**Possible Answers:**

Cannot be determined

**Correct answer:**

The coordinate of the midpoint of the line segment connecting a pair of points is

So for the pair of points and ,

we get:

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

Find the coordinate of the midpoint of the line segment connecting the pair of points

and .

**Possible Answers:**

Cannot be determined

**Correct answer:**

The coordinate of the midpoint of the line segment connecting a pair of points is

.

So for the pair of points and

we get,

### Example Question #7 : Coordinate Geometry

A line extends from the origin to . What is its midpoint?

**Possible Answers:**

**Correct answer:**

The origin is the point . We can use the regular midpoint formula with as and the given point as :

Note that since the first point is the origin, we're averaging these points with 0, or in other words just dividing by 2.

### Example Question #1 : Midpoint Formula

There is a line segment between the two points (5, 10) and (3, 6). What formula will give you the correct mid-point of the line segment?

**Possible Answers:**

**Correct answer:**

To find the mid-point given two points on the coordinate plane you are basically finding the average of the x-values and the average of the y-values. To do this follow the formula below:

With our points this gives:

### Example Question #1291 : Intermediate Geometry

A line has endpoints at (4,5) and (-6,8). Where is its midpoint?

**Possible Answers:**

**Correct answer:**

The midpoint is the point that is equidistant from each endpoint point.

We find it using a formula that computes the average of the x and y coordinates.

### Example Question #1 : Coordinate Geometry

A line segment has the endpoints and . What is the midpoint of this line segment?

**Possible Answers:**

**Correct answer:**

Recall the formula for finding a midpoint of a line segment:

The coordinates of the midpoint is just the average of the x-coordinates and the average of the y-coordinates.

Plug in the given points to find the midpoint of the line segment.
