How to do the Midpoint Formula and How to find an Endpoint with an Endpoint and Midpoint

The video tutorial covers the midpoint formula, explaining its purpose and how to use it to find the midpoint between two points on a graph. It provides examples of calculating midpoints and finding endpoints when given a midpoint. The tutorial also introduces an alternative method for finding endpoints and includes practice problems for viewers to solve.

What is the primary purpose of the midpoint formula?

• To find the area of a triangle

• To determine the midpoint between two points

• To calculate the distance between two points

• To find the slope of a line

In the example provided, what is the calculated midpoint of points A (8, 6) and B (-2, 12)?

• (6, 3)

• (0, 9)

• (3, 6)

• (3, 9)

When given one endpoint and the midpoint, which method can be used to find the other endpoint?

• Using the distance formula

• Using the area formula

• Using the slope formula

• Using the midpoint formula

If the midpoint is at (6, 0) and one endpoint is at (12, 4), what is the other endpoint?

• (0, 4)

• (6, 4)

• (12, 0)

• (0, -4)

What is the midpoint of points R (4, 3) and S (-2, -10)?

• (0, -3.5)

• (2, -3.5)

• (1, -3.5)

• (1, -7)

If the midpoint is at (12, 2) and one endpoint is at (18, 6), what is the other endpoint?

• (18, 2)

• (6, -2)

• (6, 2)

• (12, 6)

Which of the following is NOT a step in finding the midpoint between two points?

• Add the x-coordinates and divide by 2

• Multiply the coordinates by 2

• Label the coordinates as x1, y1, x2, y2

• Add the y-coordinates and divide by 2
