Use the midpoint formula to find the endpoint when given the midpoint ex 2

The video tutorial explains how to find an unknown endpoint when given one endpoint and a midpoint. It begins by plotting the known points for visualization, then introduces the midpoint formula. The instructor demonstrates how to set up equations to solve for the unknown endpoint using inverse operations. The tutorial concludes with plotting the calculated endpoint to verify its accuracy.

What is the first step the teacher suggests to solve the problem of finding the endpoint?

• Calculate the distance between points

• Plot the known points on a graph

• Directly use the midpoint formula

• Estimate the endpoint without calculations

Which formula is used to find the unknown endpoint when given a midpoint and one endpoint?

• Midpoint formula

• Quadratic formula

• Distance formula

• Slope formula

What does the teacher identify as the key to solving for the unknown coordinates?

• Using the distance formula

• Setting up separate equations for x and y

• Using a graphing calculator

• Guessing the coordinates

What operation does the teacher use to eliminate the denominator in the equations?

• Addition

• Subtraction

• Multiplication

• Division

After solving the equations, what is the calculated endpoint?

• (-9, 1)

• (-6, -2)

• (-3, -5)

• (0, 0)

How does the teacher verify the accuracy of the calculated endpoint?

• By checking with a calculator

• By using a different formula

• By plotting the point on the graph

• By recalculating the midpoint

What is the final step in the process of finding the endpoint?
