Understanding Ordered Pairs and Coordinates

The video tutorial by Mr. Holcomb covers the concept of ordered pairs, explaining the significance of the first and second coordinates. It includes a classroom activity example, exercises, and detailed examples to help students understand how to identify points using ordered pairs. The lesson concludes with a summary emphasizing the importance of the order of numbers in describing locations on a coordinate plane.

What is the first number in an ordered pair called?

• First coordinate

• Second coordinate

• Origin

• Axis

In the classroom example, what does the ordered pair (2, 3) represent?

• Row 1, Seat 2

• Row 3, Seat 1

• Row 2, Seat 3

• Row 3, Seat 2

How do you plot the point (0, 5) on a coordinate plane?

• Stay at origin, move up 5

• Move left 5, up 0

• Move right 5, up 0

• Stay at origin, move down 5

What does a negative second coordinate indicate when plotting a point?

• Move right

• Move left

• Move down

• Move up

If a point is located at (5, -2), what does the -2 indicate?

• Move down 2

• Move up 2

• Move right 2

• Move left 2

Which of the following is a common mistake when writing ordered pairs?

• Using parentheses

• Switching the order of coordinates

• Using negative numbers

• Forgetting the comma

What is the correct way to write the ordered pair for a point at x=6 and y=0?

• 6, 0

• (0, 6)

• (6, 0)

• 0, 6

What does the first coordinate in an ordered pair describe?

• Vertical direction

• Horizontal direction

• Diagonal direction

• No direction

What is the importance of the order in ordered pairs?

• It has no importance

• It describes the location on the coordinate plane

• It changes the size of the point

• It determines the color of the point

How should you represent a point at the origin?

• (0, 0)

• 0, 0

• (0, 1)

• 1, 0
