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 of numbers (x, y).

Front

What does the ordered pair (x, y) represent?

Back

The ordered pair (x, y) represents the position of a point on the coordinate plane, where 'x' is the horizontal distance from the origin and 'y' is the vertical distance from the origin.

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you identify the x-coordinate of a point?

Back

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

Front

How do you identify the y-coordinate of a point?

Back

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

Front

What is the significance of negative coordinates?

Back

Negative coordinates indicate positions that are to the left of the origin on the x-axis or below the origin on the y-axis.

Front

What is the significance of positive coordinates?

Back

Positive coordinates indicate positions that are to the right of the origin on the x-axis or above the origin on the y-axis.

Front

How do you plot the point (-2, -1.5) on a coordinate plane?

Back

To plot (-2, -1.5), move 2 units left on the x-axis and 1.5 units down on the y-axis from the origin.

Front

What does it mean for two points to be at the same x-coordinate?

Back

Two points with the same x-coordinate are vertically aligned on the coordinate plane.

Front

What does it mean for two points to be at the same y-coordinate?

Back

Two points with the same y-coordinate are horizontally aligned on the coordinate plane.
