Finding the Midpoint: Key Concepts and Examples

What does the midpoint formula calculate?

• The average of two points

• The slope of a line

• The distance between two points

• The midpoint between two points

Which of the following is the correct formula for finding the midpoint between two points (x1, y1) and (x2, y2)?

• ((x1 - x2)/2, (y1 - y2)/2)

• ((x1 + x2)/2, (y1 + y2)/2)

• (x1 + x2, y1 + y2)

• (x1 * x2, y1 * y2)

In the example given, what were the test scores used to explain the midpoint formula?

• 50% and 100%

• 60% and 80%

• 40% and 90%

• 70% and 85%

How do you calculate the average of two test scores?

• Multiply the scores and divide by 2

• Add the scores and multiply by 2

• Subtract the lower score from the higher score

• Add the scores and divide by 2

What are the coordinates of the first point used in the example to find the midpoint?

• (-5, -6)

• (0, 1)

• (5, 8)

• (3, 4)

What is the result of adding the x-coordinates of the points (-5, -6) and (5, 8) and dividing by 2?

• 5

• -5

• 0

• 10

What is the midpoint of the points (-5, -6) and (5, 8)?

• (0, 1)

• (1, 0)

• (0, -1)

• (-1, 0)

Why does the midpoint in the example lie on the y-axis?

• Because the y-coordinates are symmetric around zero

• Because the x-coordinates are symmetric around zero

• Because the y-coordinates are equal

• Because the x-coordinates are equal

What is a good method to verify the midpoint calculation during an exam?

• Ask a friend

• Sketch a picture

• Memorize the formula

• Use a calculator

What should you do if you have questions about the midpoint formula?

• Search online

• Ask your teacher

• Post them in the comments

• Ignore them
