Graphing on coordinate plane

Front

What is the coordinate plane?

Back

The coordinate plane is a two-dimensional surface formed by the intersection of a horizontal axis (x-axis) and a vertical axis (y-axis), used to graph points, lines, and curves.

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, where 'x' represents the horizontal position and 'y' represents the vertical position.

Front

What does the x-axis represent in the coordinate plane?

Back

The x-axis is the horizontal axis of the coordinate plane, where the y-coordinate is zero.

Front

What does the y-axis represent in the coordinate plane?

Back

The y-axis is the vertical axis of the coordinate plane, where the x-coordinate is zero.

Front

How do you identify the four quadrants of the coordinate plane?

Back

The four quadrants are identified as follows: 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 ordered pair for point B if it is located at (3, 4)?

Back

The ordered pair for point B is (3, 4), where 3 is the x-coordinate and 4 is the y-coordinate.

Front

What is the distance from the origin to the point (0, -6)?

Back

The distance from the origin (0, 0) to the point (0, -6) is 6 units.

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction, denoted as |x|.

Front

What is the significance of the point (0, 0) in the coordinate plane?

Back

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

Front

How do you determine which quadrant a point lies in?

Back

To determine the quadrant of a point (x, y), check the signs of x and y: if both are positive, it's in Quadrant I; if x is negative and y is positive, it's in Quadrant II; if both are negative, it's in Quadrant III; if x is positive and y is negative, it's in Quadrant IV.
