Distance in the Coordinate Plane

Mr. Bell's math lesson focuses on finding the distance between two points on a coordinate plane using absolute value. The video begins with an introduction to the concept and a review of absolute value, emphasizing its always positive nature. Mr. Bell highlights common mistakes in graphing, such as incorrect plotting order. He demonstrates how to plot points and calculate distances using absolute value, providing examples with points having the same x or y coordinates. The lesson concludes with a summary of the key concepts and encourages students to rewatch if needed.

What is the key concept for finding the distance between two points on a coordinate plane?

• Division

• Square root

• Absolute value

• Multiplication

What does absolute value represent?

• The positive distance from zero

• The total distance between two numbers

• The square of the distance from zero

• The negative distance from zero

What is the result of the absolute value of -3?

• 9

• 3

• -3

• 0

What does the absolute value of a number indicate in the context of a coordinate plane?

• Its direction from the origin

• Its distance from the origin

• Its numerical value without considering distance

• Its potential to be a negative number

What is a common mistake when plotting points on a coordinate plane?

• Ignoring the origin

• Plotting points without counting

• Moving along the x-axis first

• Moving along the y-axis first

How do you correctly plot a point on a coordinate plane?

• Y-axis then x-axis

• Directly to the point without axes

• Randomly, as it does not matter

• X-axis then y-axis

Why is it important to move along the x-axis before the y-axis when plotting a point?

• Because it's easier

• To follow tradition

• To ensure accuracy

• It's not important

How can absolute value be used to find the distance between two points with the same X values?

• By finding the absolute value of the difference between Y values

• By adding the Y values

• By multiplying the Y values

• By subtracting the Y values

What is the distance between two points if their Y values are 4 and 0, respectively, and they share the same X value?

• 2 units

• 4 units

• 0 units

• 8 units

If two points have the same Y value but different X values, how do you find the distance between them?

• By subtracting the X values

• By dividing the X values

• By finding the absolute value of the difference between X values

• By adding the X values
