Introduction to the Coordinate Plane: Plotting Ordered Pairs

This video tutorial explains how to locate points on a coordinate plane by plotting ordered pairs. It begins with an introduction to coordinate planes and number lines, explaining positive and negative numbers. The tutorial then describes the axes, the origin, and how to read ordered pairs. It provides examples of plotting ordered pairs, highlighting common mistakes such as reversing the order of axes. The lesson emphasizes the importance of moving along the x-axis first, followed by the y-axis, to correctly plot points.

What is the label for the horizontal axis on a coordinate plane?

• z-axis

• y-axis

• w-axis

• x-axis

What is the origin on a coordinate plane?

• The point where the x-axis and y-axis intersect

• The point at the top of the y-axis

• The point where the y-axis ends

• The point at the end of the x-axis

How do you plot the ordered pair (3, 5) on a coordinate plane?

• Move 3 spaces left and 5 spaces down

• Move 3 spaces right and 5 spaces up

• Move 5 spaces right and 3 spaces up

• Move 5 spaces left and 3 spaces down

If an ordered pair is (-1, 4), which direction do you move first?

• Down

• Left

• Up

• Right

What common mistake do students make when plotting ordered pairs?

• Using positive numbers for both axes

• Using negative numbers for both axes

• Moving on the x-axis first

• Moving on the y-axis first
