Plotting and Identifying 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 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

How do you identify the coordinates of a point?

Back

Coordinates are written as (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does the point (0, 0) represent?

Back

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

Front

How do you plot the point (3, 4)?

Back

Start at the origin, move 3 units to the right (positive x-direction), then move 4 units up (positive y-direction).

Front

What is the significance of the x-axis?

Back

The horizontal line in the coordinate plane where y = 0.

Front

What is the significance of the y-axis?

Back

The vertical line in the coordinate plane where x = 0.

Front

What does a negative x-coordinate indicate?

Back

The point is located to the left of the origin.

Front

What does a negative y-coordinate indicate?

Back

The point is located below the origin.

Front

How do you determine which quadrant a point is in?

Back

By examining the signs of the x and y coordinates: both positive in Quadrant I, x negative and y positive in Quadrant II, both negative in Quadrant III, and x positive and y negative in Quadrant IV.
