Finding Distance on the Coordinate Plane

This video tutorial by Mr. Math Blog covers lesson 39 on finding distances on a coordinate plane. It explains how to calculate the distance between two points on horizontal and vertical lines using absolute values. The tutorial also demonstrates how to verify these calculations and apply the method to points in different quadrants. The importance of context in problem-solving is emphasized, ensuring students understand the units of measurement.

What is the primary method to find the distance between two points on a coordinate plane?

• Absolute value

• Subtraction

• Division

• Multiplication

If two points lie on a horizontal line and have the same y-coordinate, how do you calculate the distance between them?

• By adding their x-coordinates

• By subtracting their y-coordinates

• By finding the absolute value of the difference of their x-coordinates

• By multiplying their x-coordinates

How can the concept of absolute value be used to find the distance between two points?

• By always converting distances to negative values

• By dividing the coordinates

• By ensuring the distance is represented as a positive number

• By multiplying the coordinates

What is the distance between points A (-4, 3) and B (5, 3)?

• 4 miles

• 1 mile

• 9 miles

• 5 miles

How can you verify the calculated distance between two points on a coordinate plane?

• By guessing

• By counting the squares between the points

• By asking someone else

• By measuring with a ruler

What is the distance from point B to the x-axis if B is at (5, 3)?

• 2 miles

• 8 miles

• 5 miles

• 3 miles

In the context of the problem, why is it important to specify the units of measurement (e.g., miles) when answering a question?

• To avoid confusion with other measurements

• Because it's a requirement

• To make the answer look complete

• To practice writing units

How does the concept of absolute value assist in finding distances on a coordinate plane?

• By converting all distances to zero

• By ensuring distances are always shown as positive values

• By reducing the number of steps in calculation

• By making calculations more complex

If two points are vertical to each other, how do you determine the distance between them?

• By adding their y-coordinates

• By finding the absolute value of the difference of their y-coordinates

• By subtracting their x-coordinates

• By dividing their y-coordinates

What is the distance between points C and D if they are vertical to each other and their x-coordinate is 8?

• 8 units

• 7 units

• 10 units

• 5 units
