Graphing on 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 an ordered pair (x, y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does the first number in an ordered pair represent?

Back

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

Front

What does the second number in an ordered pair represent?

Back

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

Front

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

Back

Start at the origin (0, 0), move 3 units to the right (positive x-direction), then move 4 units up (positive y-direction).

Front

What is the significance of the origin in the coordinate plane?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect, serving as the reference point for all other points.

Front

In which quadrant is the point (5, -3) located?

Back

Quadrant IV, where x is positive and y is negative.

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

How do you determine the quadrant of the point (-2, 3)?

Back

Since x is negative and y is positive, the point is in Quadrant II.
