Coordinate Plane Basics

In this video, Mr. Jay explains how to plot points on a coordinate plane. He begins with a brief review of the x-axis and y-axis, emphasizing the order of coordinates. Through six examples, he demonstrates plotting points with various coordinates, highlighting the importance of starting from the origin and moving horizontally first, then vertically. The video concludes with a recap of the key points and a reminder of the coordinate order.

What is the orientation of the x-axis on a coordinate plane?

• Vertical

• Diagonal

• Horizontal

• Circular

In the ordered pair (4, 7), which number represents the y-coordinate?

• 0

• 7

• 4

• None of the above

How do you move from the origin to plot the point (3, -9)?

• Right 3, Up 9

• Left 3, Up 9

• Left 3, Down 9

• Right 3, Down 9

What is the x-coordinate in the ordered pair (-9, 3)?

• 9

• 0

• 3

• -9

To plot the point (-5, -6), which direction do you move on the y-axis?

• Down 5

• Up 6

• Down 6

• Up 5

If the x-coordinate is 0, where do you start plotting on the x-axis?

• At the origin

• At x = 1

• At x = -1

• At x = 10

What is the y-coordinate in the ordered pair (0, -2)?

• 2

• -1

• 0

• -2

How do you move from the origin to plot the point (-8, 10)?

• Left 8, Up 10

• Left 8, Down 10

• Right 8, Down 10

• Right 8, Up 10

What is the x-coordinate in the ordered pair (-8, 10)?

• 8

• 0

• 10

• -8

What should you remember about the order of coordinates in an ordered pair?

• They are always the same

• Order doesn't matter

• X comes before Y

• Y comes before X
