Graphing points

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).

Front

What are the coordinates of a point?

Back

Coordinates are a pair of numbers (x, y) that define the position of a point on the coordinate plane.

Front

What does the x-coordinate represent?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

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

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

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

Back

The point (0, y) lies on the y-axis.

Front

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

Back

The point (x, 0) lies on the x-axis.

Front

How do you identify a point in Quadrant I?

Back

A point in Quadrant I has both coordinates positive (x > 0, y > 0).

Front

How do you identify a point in Quadrant II?

Back

A point in Quadrant II has a negative x-coordinate and a positive y-coordinate (x < 0, y > 0).
