Graphing 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 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 coordinates of a point on the coordinate plane?

Back

To identify the coordinates of a point, find its horizontal position (x) along the x-axis and its vertical position (y) along the y-axis, then write them as an ordered pair (x, y).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate plane where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate plane where the x-coordinate is zero.

Front

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

Back

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

Front

What shape is formed by the points (-6, -5), (-4, 0), and (-2, -5)?

Back

The points form a triangle.

Front

What are the coordinates for POINT I if it is located at (-2, -5)?

Back

The coordinates for POINT I are (-2, -5).

Front

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

Back

It means the point is located in the fourth quadrant of the coordinate plane.
