Calculating Distance on the Coordinate Plane

This video tutorial covers the process of finding the distance between two points on a coordinate plane. It begins with a brief introduction and instructions for note-taking. The lesson then reviews how to plot points on the coordinate plane, emphasizing the importance of starting at the origin. Two examples are provided to demonstrate the calculation of distance using the Pythagorean theorem. The video concludes with a reminder to check notes and complete checkpoint questions.

What is the origin on a coordinate plane?

• The point where the X and Y axes intersect

• The point where the X axis ends

• The point where the Y axis ends

• The point at the top right corner of the plane

In the first example, what is the length of the horizontal leg of the right triangle?

• 8 units

• 15 units

• 13 units

• 9 units

What is the formula used to find the distance between two points?

• Distance = a^2 + b^2

• Distance = √(a^2 - b^2)

• Distance = a^2 - b^2

• Distance = √(a^2 + b^2)
