Graph Rational Numbers on a Coordinate Plane

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 (x, y), start at the origin (0, 0). Move 'x' units along the x-axis (right for positive, left for negative) and then 'y' units up (positive) or down (negative) along the y-axis.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero. It is used to measure the horizontal position of points.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero. It is used to measure the vertical position of points.

Front

What are quadrants in a coordinate plane?

Back

The coordinate plane is divided into four quadrants: Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), Quadrant IV (positive x, negative y).

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. It serves as the reference point for all other points on the plane.

Front

How do you identify the coordinates of a point?

Back

The coordinates of a point are identified by its position relative to the x-axis and y-axis, expressed as (x, y).

Front

What is the significance of negative coordinates?

Back

Negative coordinates indicate positions to the left of the y-axis (for x) or below the x-axis (for y) on the coordinate plane.

Front

How do you convert a mixed number to an improper fraction?

Back

To convert a mixed number to an improper fraction, multiply the whole number by the denominator, add the numerator, and place the result over the original denominator.
