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 of numbers (x, y).

Front

What are the four quadrants of a 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 identified as an ordered pair (x, y), where 'x' represents the horizontal position and 'y' represents the vertical position on the coordinate plane.

Front

What does the point (0, 0) represent?

Back

The point (0, 0) is known as the origin, where the x-axis and y-axis intersect.

Front

What is the significance of 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. They are used to plot points and define the location of points in relation to each other.

Front

How do you determine which quadrant a point is in?

Back

To determine the quadrant, look at the signs of the x and y coordinates: Quadrant I (both positive), Quadrant II (x negative, y positive), Quadrant III (both negative), Quadrant IV (x positive, y negative).

Front

What are the coordinates of a point in Quadrant I?

Back

In Quadrant I, both coordinates are positive, for example, (3, 4).

Front

What are the coordinates of a point in Quadrant II?

Back

In Quadrant II, the x-coordinate is negative and the y-coordinate is positive, for example, (-3, 5).

Front

What are the coordinates of a point in Quadrant III?

Back

In Quadrant III, both coordinates are negative, for example, (-2, -3).

Front

What are the coordinates of a point in Quadrant IV?

Back

In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative, for example, (4, -2).
