Understanding Points and Ordered Pairs

This video tutorial introduces the concept of points and ordered pairs in the coordinate plane. It explains how to plot points using the x-axis and y-axis, and how to determine the coordinates of points. The tutorial also covers identifying coordinates from plotted points and demonstrates using a graphing calculator to verify plotted points. The video aims to help viewers understand the basics of graphing and coordinate systems.

What is the name of the point where the X-axis and Y-axis intersect?

• Origin

• Intersection

• Vertex

• Center

Which axis is horizontal in the coordinate plane?

• X-axis

• W-axis

• Z-axis

• Y-axis

In the ordered pair (4, 3), what does the number 4 represent?

• W-coordinate

• X-coordinate

• Z-coordinate

• Y-coordinate

How do you move on the coordinate plane if the X-coordinate is negative?

• Move up

• Move right

• Move down

• Move left

If a point has coordinates (-3, 2), in which direction do you move first?

• Down

• Left

• Right

• Up

What is the Y-coordinate of the point (0, -2)?

• -2

How can you identify the coordinates of a plotted point?

• By measuring with a ruler

• By using a compass

• By drawing lines to the axes

• By guessing

What is the X-coordinate of point F if it is located at (7, 0)?
