### Example Question #1331 : Intermediate Geometry

A line segment has an endpoint at and midpoint at . Find the coordinates of the other endpoint.

**Possible Answers:**

**Correct answer:**

Recall how to find the midpoint of a line segment:

,

where are the endpoints.

Let's first focus on the coordinate of the other endpoint. Using the information given by the question, we can write the following equation:

Solve for .

Next, find the coordinate of the other endpoint. Using the information given by the question, we can write the following equation:

The second endpoint must be at .

### Example Question #55 : Coordinate Geometry

A line segment on the coordinate plane has an endpoint at ; its midpoint is at .

True or false: Its other endpoint is located at .

**Possible Answers:**

False

True

**Correct answer:**

True

The midpoint of a line segment with endpoints and is located at .

Therefore, set

and

In the first equation, set and solve for :

Multiply both sides by 2:

Subtract 3.8 from both sides:

In the second equation, set and solve for :

Multiply both sides by 2:

Add 1.7 to both sides:

The other endpoint is indeed at , so the statement is true.
