Example Question #53 : How To Find The Midpoint Of A Line Segment

Two points,  and , are connected to form a line.  What is the midpoint?

Possible Answers:

Correct answer:

Explanation:

Write the midpoint formula.  The midpoint is the center of the line segment.

Substitute the values of the coordinates.

The midpoint is:  

Example Question #55 : How To Find The Midpoint Of A Line Segment

Find the midpoint of the line segment formed by the points

(-1, -3) and (3, 3).

 

Possible Answers:

(2, 2)

(2, 0)

(1, 0)

(-4, -6)

(1, -1)

Correct answer:

(1, 0)

Explanation:

To find the midpoint between two points, we use the following formula:

where  and  are the points given.  So, given the points

(-1, -3) and (3, 3), we can substitute into the formula.

Therefore, the midpoint between (-1, -3) and (3, 3) is (1, 0).

Example Question #54 : How To Find The Midpoint Of A Line Segment

Find the midpoint of a line segment with the following endpoints:

Possible Answers:

Correct answer:

Explanation:

Finding the midpoint of a line segment only requires that we find the midpoint, or average of both the x and y components. In order to do that, we use the following formula:

For the points (2,6) and (12,12) plug in the numbers and solve:
