Coordinate Geometry Concepts

This video tutorial teaches how to plot points on a coordinate plane. It begins with an overview of the coordinate plane, explaining the x-axis, y-axis, and the origin. The tutorial then provides step-by-step instructions on plotting points, including examples with different coordinates. Special cases, such as points lying on the axes or at the origin, are also discussed. An alternative method for plotting points using intersecting lines is introduced. The video concludes with a transition to finding coordinates of points.

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

• Crosspoint

• Intersection

• Origin

• Center

On the x-axis, which direction is considered positive?

• Right

• Up

• Left

• Down

If a point has a negative x-coordinate, which direction should you move from the origin?

• Right

• Left

• Down

• Up

What is the key concept to remember when plotting points?

• Move diagonally

• Move randomly

• Move horizontally first

• Move vertically first

If the y-coordinate is positive, which direction should you move?

• Right

• Left

• Down

• Up

To plot the point (4, 3), how many units do you move up after moving right?

• 2

• 3

• 4

• 5

For point B with coordinates (-4, -3), which direction do you move first?

• Down

• Right

• Left

• Up

What is the y-coordinate of point D if it is plotted at (5, -5)?

• 1

• 0

• -5

• 5

For point E with coordinates (2, 0), which axis does it lie on?

• x-axis

• y-axis

• None
