How to Find the Midpoint

The video tutorial guides viewers through solving a standardized math test question by finding the midpoint of a segment. It begins with an introduction to the problem, explaining that point S is the midpoint of segment RT, with given coordinates for points R and T. The tutorial then explains the concept of a midpoint, which is the average of the x and y coordinates of the endpoints. The instructor demonstrates the calculation process, adding the coordinates and dividing by two to find the midpoint. The video concludes with the final calculation and the correct answer choice.

What is the role of point S in the segment RT?

• Point S is the endpoint of segment RT.

• Point S is outside the segment RT.

• Point S is the starting point of segment RT.

• Point S is the midpoint of segment RT.

How do you find the midpoint of a segment?

• By dividing the coordinates of the endpoints.

• By multiplying the coordinates of the endpoints.

• By subtracting the coordinates of the endpoints.

• By averaging the coordinates of the endpoints.

What is the first step in calculating the midpoint of a segment?

• Add the x-coordinates of the endpoints.

• Divide the x-coordinates of the endpoints.

• Multiply the x-coordinates of the endpoints.

• Subtract the x-coordinates of the endpoints.

What is the result of adding the y-coordinates -2 and -4?

• -12

• -16

• -8

• -6

What is the final midpoint of segment RT given the coordinates?

• (-6, -7)

• (-7, -6)

• (-8, -9)

• (-9, -8)
