Graph Rational Numbers on a Coordinate Plane- L2

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the plane is defined by an ordered pair (x, y).

Front

What does an ordered pair represent?

Back

An ordered pair (x, y) represents a specific point on the coordinate plane, where 'x' is the horizontal position and 'y' is the vertical position.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0, 0). Move 'x' units along the x-axis and 'y' units up or down along the y-axis. Mark the point where you end up.

Front

What is the x-coordinate?

Back

The x-coordinate is the first number in an ordered pair (x, y) that indicates the horizontal position of a point on the coordinate plane.

Front

What is the y-coordinate?

Back

The y-coordinate is the second number in an ordered pair (x, y) that indicates the vertical position of a point on the coordinate plane.

Front

What does it mean if a point has a negative x-coordinate?

Back

A negative x-coordinate means the point is located to the left of the origin on the x-axis.

Front

What does it mean if a point has a negative y-coordinate?

Back

A negative y-coordinate means the point is located below the origin on the y-axis.

Front

What is the origin in a coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.

Front

How do you identify the quadrant of a point?

Back

The quadrant of a point is determined by the signs of its coordinates: Quadrant I (positive, positive), Quadrant II (negative, positive), Quadrant III (negative, negative), Quadrant IV (positive, negative).

Front

What is the significance of the point (0, y)?

Back

The point (0, y) lies on the y-axis and represents a vertical position with no horizontal displacement.
