Understanding Cartesian Coordinates

This video tutorial introduces Cartesian coordinates, explaining how they are used to specify locations in two dimensions. It covers the concepts of the origin and axes, and demonstrates how to plot points on a graph. The tutorial includes exercises to practice graphing points and identifying coordinates, and concludes with a brief mention of an adaptive program for further practice.

What is the primary purpose of Cartesian coordinates?

• To specify locations in four-dimensional space

• To specify locations in three-dimensional space

• To specify locations in two-dimensional space

• To specify locations in one-dimensional space

What is the term used for the reference point in Cartesian coordinates?

• Vertex

• Origin

• Center

• Axis

What is the coordinate of the origin in Cartesian coordinates?

• (1, 0)

• (1, 1)

• (0, 0)

• (0, 1)

In Cartesian coordinates, what does a negative x-coordinate indicate?

• A point below the origin

• A point to the right of the origin

• A point above the origin

• A point to the left of the origin

If a point is located at (3, -5), what does the -5 represent?

• 5 units up

• 5 units down

• 5 units to the right

• 3 units to the right

What is the convention for naming the horizontal axis in Cartesian coordinates?

• z-axis

• y-axis

• w-axis

• x-axis

What does a positive y-coordinate indicate in Cartesian coordinates?

• A point below the origin

• A point to the right of the origin

• A point above the origin

• A point to the left of the origin

If a point is at (-4, -4), what does the first coordinate represent?

• 4 units to the right

• 4 units up

• 4 units to the left

• 4 units down

Which of the following points is not graphed if the coordinates are (-8, -9)?

• (-6, -6)

• (3, -1)

• (1, 0)

• (-8, -9)

In the adaptive program, which point was identified as not graphed?

• (4, 2)

• (3, 6)

• (-1, 5)

• (4, 3)
