Coordinate Plane Concepts and Quadrants

This video tutorial covers lesson 15 on locating ordered pairs on the coordinate plane. It explains the concept of the coordinate plane, the x and y axes, and the origin. The tutorial discusses ordered pairs and how they describe the location of points on the plane. It includes exercises on graphing points on the x and y axes and explores the four quadrants of the coordinate plane, highlighting the characteristics of each quadrant.

What is the point called where the x-axis and y-axis intersect?

• Intersection

• Center

• Origin

• Vertex

In an ordered pair (x, y), what does the 'x' represent?

• None of the above

• Diagonal position

• Horizontal position

• Vertical position

What is true about any point that lies on the x-axis?

• It is always positive

• It is always negative

• It has an x-coordinate of zero

• It has a y-coordinate of zero

If a point has coordinates (0, 5), on which axis does it lie?

• Neither axis

• Both axes

• x-axis

• y-axis

How many quadrants are there in a coordinate plane?

• Five

• Four

• Three

• Two

Which quadrant contains points with both positive x and y coordinates?

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

What is the characteristic of points in Quadrant II?

• Negative x, negative y

• Positive x, negative y

• Negative x, positive y

• Positive x, positive y

Which quadrant would the point (-3, -5) be located in?

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

What is the pattern for points in Quadrant IV?

• Positive x, negative y

• Negative x, negative y

• Negative x, positive y

• Positive x, positive y

Which of the following points is in Quadrant I?

• (-3, -2)

• (2, 3)

• (3, -2)

• (-2, 3)
