How to determine the endpoint, given one endpoint and midpoint

The video tutorial addresses a common problem where students struggled to find an endpoint given a midpoint and one endpoint. The teacher explains the importance of understanding the problem, demonstrates plotting points, and walks through the midpoint formula. The tutorial concludes with solving for the unknown endpoint using algebraic manipulation.

What is the first step suggested by the teacher to understand the problem better?

• Skip the problem

• Ask a friend for help

• Plot the given points

• Memorize the formula

What does the midpoint formula help you find?

• The slope of a line

• The area of a triangle

• The distance between two points

• The midpoint between two points

If you know one endpoint and the midpoint, what do you need to find the other endpoint?

• The coordinates of the known endpoint

• The coordinates of the midpoint

• The distance between the points

• The slope of the line

What operation is performed to eliminate the denominator in the equation for finding the missing endpoint?

• Addition

• Division

• Subtraction

• Multiplication

What are the coordinates of the missing endpoint found in the example?

• (1, 6)

• (-1, 6)

• (1, -6)

• (-1, -6)
