Understanding the Coordinate Plane

The video tutorial introduces the coordinate plane, a two-dimensional graphing platform formed by two perpendicular number lines, the x-axis and y-axis. It explains how to plot points using ordered pairs of coordinates, which specify locations on the plane. The tutorial covers the four quadrants of the plane, each defined by the signs of the x and y coordinates. The historical context of the Cartesian plane, named after René Descartes, is also discussed.

What is the primary difference between a number line and a coordinate plane?

• A number line is one-dimensional, while a coordinate plane is two-dimensional.

• A number line is used for graphing, while a coordinate plane is not.

• A number line is two-dimensional, while a coordinate plane is one-dimensional.

• A number line uses coordinates, while a coordinate plane does not.

How are coordinates formatted when plotting points on a coordinate plane?

• As two numbers inside square brackets, separated by a dash.

• As two numbers inside parentheses, separated by a comma.

• As two numbers separated by a semicolon.

• As a single number inside brackets.

What is the significance of the origin in the coordinate plane?

• It is the highest point on the coordinate plane.

• It is the point where all coordinates are negative.

• It is the point where the x-axis and y-axis intersect.

• It is the point where all coordinates are positive.
