Plotting 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).

Front

What are the x-axis and y-axis?

Back

The x-axis is the horizontal line on the coordinate plane, while the y-axis is the vertical line.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, written in the form (x, y).

Front

How do you plot a point on the coordinate plane?

Back

To plot a point, start at the origin (0,0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

What does the first number in an ordered pair represent?

Back

The first number represents the x-coordinate, indicating the horizontal position.

Front

What does the second number in an ordered pair represent?

Back

The second number represents the y-coordinate, indicating the vertical position.

Front

What is the origin in the coordinate plane?

Back

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

Front

What quadrant is point (3, -2) located in?

Back

Point (3, -2) is located in Quadrant IV.

Front

What quadrant is point (-3, 4) located in?

Back

Point (-3, 4) is located in Quadrant II.

Front

What is the significance of the signs of coordinates?

Back

The signs indicate the location of the point relative to the axes: positive x and y are in Quadrant I, negative x and positive y in Quadrant II, etc.
