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 does the first number in an ordered pair represent?

• The quadrant number.

• The distance from the origin.

• The position on the x-axis.

• The position on the y-axis.

When plotting the point (3, 2), how do you move from the origin?

• 3 units right, 2 units up

• 2 units up, 3 units right

• 3 units up, 2 units right

• 2 units right, 3 units up

In which quadrant would you find the point (-4, 3)?

• Quadrant II

• Quadrant III

• Quadrant IV

• Quadrant I

Which quadrant contains points with both negative x and y values?

• Quadrant III

• Quadrant II

• Quadrant I

• Quadrant IV

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.

Who is credited with developing the concept of the Cartesian plane?

• Albert Einstein

• Galileo Galilei

• Rene Descartes

• Isaac Newton

What is the ordered pair for the origin?

• (1, 1)

• (0, 1)

• (1, 0)

• (0, 0)

How do you find the point described by the ordered pair (2, 3)?

• Move 3 units right, then 2 units up

• Move 3 units up, then 2 units right

• Move 2 units right, then 3 units up

• Move 2 units up, then 3 units right
