Understanding the Coordinate Plane

This video tutorial introduces the concept of the coordinate plane and ordered pairs, emphasizing the importance of the x and y coordinates. It explains how to plot points on the plane, relate the coordinate plane to a number line, and understand the significance of the origin. The tutorial also covers points on the x-axis and y-axis, and explains the four quadrants of the coordinate plane, using Roman numerals and a counter-clockwise naming convention.

What is the correct order of coordinates in an ordered pair?

• y, x

• x, y

• y, z

• z, x

If a point is located at (1, 4), what does this mean?

• 1 up, 4 right

• 1 right, 4 up

• 4 right, 1 up

• 4 up, 1 right

How would you describe the point (0, 5)?

• 0 up, 5 right

• 0 right, 5 up

• 5 up, 0 right

• 5 right, 0 up

What does a negative x-coordinate indicate?

• Up

• Left

• Right

• Down

What is the significance of the origin in the coordinate plane?

• It is where x and y are both positive

• It is where y is zero

• It is where x is zero

• It is where x and y are both zero

Why is the order of coordinates in an ordered pair important?

• It changes the size of the point

• It affects the position of the point

• It has no significance

• It determines the color of the point

What is common among all points on the x-axis?

• x-coordinate is zero

• y-coordinate is zero

• Both coordinates are zero

• Coordinates are negative

What is common among all points on the y-axis?

• y-coordinate is zero

• Both coordinates are zero

• Coordinates are positive

• x-coordinate is zero

What is unique about the origin?

• Coordinates are mixed

• Both coordinates are zero

• Both coordinates are negative

• Both coordinates are positive

How are the quadrants of the coordinate plane numbered?

• From bottom to top

• Randomly

• Counter-clockwise

• Clockwise
