Midpoint and Distance Calculations

This video tutorial explains how to find the midpoint and distance between two points using formulas. It begins with an introduction to the concepts and emphasizes the importance of correctly labeling points. The video provides a detailed walkthrough of calculating the distance between two points using the distance formula, followed by a guide on finding the midpoint. The tutorial concludes with practice problems to reinforce the concepts learned.

What are the two main topics covered in this video?

• Graphing linear equations

Where can you find the formulas for midpoint and distance?

• Page 10 of the textbook

• Page 18 of the formula booklet

• Page 5 of the workbook

• Page 22 of the guidebook

Why is it important to label points as x1, y1, x2, y2?

• To avoid confusion with other variables

• To ensure correct application of formulas

• To make the graph look neat

• To match the textbook examples

What is the correct way to label the coordinates of two points?

• y1, y2, x1, x2

• x2, y2, x1, y1

• x1, y1, x2, y2

• x1, x2, y1, y2

What is the formula for calculating the distance between two points?

• Square root of (x2 - x1)^2 + (y2 - y1)^2

• Square root of (x1 - x2)^2 + (y1 - y2)^2

• (x2 - x1) + (y2 - y1)

• (x1 + x2) / 2, (y1 + y2) / 2

What is the distance between points A(2, 5) and B(7, 12)?

• 10.2

• 9.1

• 8.6

• 7.5

How should you round the distance if not specified in the question?

• To the nearest whole number

• To one decimal place

• To two decimal places

• To three decimal places

What is the formula for finding the midpoint between two points?

• (x1 + x2) / 2, (y1 + y2) / 2

• (x1 + x2), (y1 + y2)

• (x2 - x1) / 2, (y2 - y1) / 2

• (x1 - x2) / 2, (y1 - y2) / 2

What is the midpoint between points A(2, 5) and B(7, 12)?

• (4.5, 8.5)

• (5, 9)

• (3.5, 7.5)

• (6, 10)

What is the first step in finding the midpoint?

• Subtract the coordinates

• Add the x-coordinates and divide by 2

• Multiply the coordinates

• Divide the y-coordinates by 2
