Graphing Points on the Coordinate Plane

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs.

Front

What are the axes in a coordinate plane?

Back

The x-axis (horizontal) and y-axis (vertical) are the two perpendicular lines that define the coordinate plane.

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent the position of a 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 the coordinate plane?

Back

Start at the origin (0,0), move 'x' units along the x-axis, and then 'y' units up (if positive) or down (if negative) to locate the point.

Front

What does the point (0, 0) represent?

Back

The origin, which is the point where the x-axis and y-axis intersect.

Front

What are the four quadrants of the coordinate plane?

Back

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 x-coordinate?

Back

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

Front

What is the significance of the y-coordinate?

Back

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

Front

How do you identify a point in Quadrant I?

Back

Both coordinates are positive (x > 0, y > 0).

Front

How do you identify a point in Quadrant II?

Back

The x-coordinate is negative and the y-coordinate is positive (x < 0, y > 0).
