Plotting Points on a Coordinate Plane

The video tutorial introduces the concept of a coordinate system, explaining the x-axis and y-axis, and how they represent input and output values. It covers the definition of ordered pairs and the origin point, and demonstrates how to plot points on a grid using ordered pairs. The tutorial includes examples to illustrate the process of plotting different ordered pairs.

What is the primary function of the x-axis in a coordinate system?

• It represents horizontal movement.

• It is used for circular movement.

• It represents vertical movement.

• It is used for diagonal movement.

In a coordinate system, what is the point (0, 0) commonly referred to as?

• The axis point

• The origin

• The midpoint

• The center

How do you determine the x and y values in an ordered pair?

• Both numbers are y values.

• The first number is y, and the second is x.

• The first number is x, and the second is y.

• Both numbers are x values.

When plotting the point (3, 4) on a coordinate grid, what is the correct sequence of movements?

• Move up 3, then right 4

• Move right 3, then up 4

• Move down 3, then left 4

• Move left 3, then down 4

If you have the ordered pair (2, -3), how would you plot it on a coordinate grid?

• Move up 2, then right 3

• Move down 2, then left 3

• Move left 2, then up 3

• Move right 2, then down 3
