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.

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
