### Example Question #1 : Coordinate Geometry

What would be the midpoint of a line segment with endpoints at and ?

**Possible Answers:**

**Correct answer:**

The midpoint of a line segment is halfway between the two values and halfway between the two values.

Mathematically, that would be the average of each coordinate: .

Plug in the values from the given points and solve.

We can simplify the fraction to give our final answer.

The midpoint of a line segment is halfway between the two values and halfway between the two values.

Mathematically, that would be the average of each coordinate: .

Plug in the values from the given points and solve.

Simplify the fractions to get the final answer.

### Example Question #3 : Coordinate Geometry

If a line has a midpoint at , and the endpoints are and , what is the value of ?

**Possible Answers:**

**Correct answer:**

The midpoint of a line segment is halfway between the two values and halfway between the two values.

Mathematically, that would be the average of the coordinates: .

Plug in the values from the given points.

Now we can solve for the missing value.

The values reduce, so both values equal . Now we need to create a new equation to solve for the value.

Multiply both sides by to solve.

### Example Question #6 : Coordinate Geometry

Find the midpoint between (4, 3) and (6, 9).

**Possible Answers:**

**Correct answer:**

Add up the 's and divide in half, which results in 5. Do the same to the 's and you get 6. Put the and in an ordered pair so that your answer is (5, 6).

### Example Question #1 : Coordinate Geometry

What is the midpoint of the line segment which connects and ?

**Possible Answers:**

**Correct answer:**

To find the midpoint of a line segment, we find the average of the x and y coordinates of the endpoints. The average of two numbers is the sum of those numbers divided by . Thus, to find the x-coordinate of our midpoint, we find the average of and , and we get .

To find the y-coordinate of our midpoint, we find the average of and , which is .

Thus, our midpoint is
