Coordinates of Point F: A Comprehensive Guide

Introduction: Understanding the Cartesian Plane and Quadrants

The Cartesian plane is a two-dimensional coordinate system used to represent points in space. It consists of two perpendicular lines, called the x-axis and y-axis, that intersect at a point called the origin. The plane is divided into four quadrants, each bounded by one of the axes and the origin.

Determining the Quadrant of Point F

To determine the quadrant of a point, first identify the signs of its x- and y-coordinates.

  • First Quadrant (Q1): Both x and y coordinates are positive (++).
  • Second Quadrant (Q2): x-coordinate is negative (-) and y-coordinate is positive (+).
  • Third Quadrant (Q3): Both x and y coordinates are negative (–).
  • Fourth Quadrant (Q4): x-coordinate is positive (+) and y-coordinate is negative (-).

Example: Finding the Coordinates of Point F

Consider the following coordinates of a point F:

(2, -3)
  • The x-coordinate is positive (+2).
  • The y-coordinate is negative (-3).

Therefore, point F lies in the Second Quadrant (Q2).

Special Cases

On the Coordinate Axis:

If either the x- or y-coordinate is zero, the point lies on the corresponding axis.

  • If the x-coordinate is zero, the point is on the y-axis.
  • If the y-coordinate is zero, the point is on the x-axis.

At the Origin:

If both the x- and y-coordinates are zero, the point is at the origin.

Transformation of Coordinates

  • Reflection over the x-axis: Changes the sign of the y-coordinate while keeping the x-coordinate the same.
  • Reflection over the y-axis: Changes the sign of the x-coordinate while keeping the y-coordinate the same.
  • Rotation by 90 degrees: Exchanges x- and y-coordinates while preserving their signs.
  • Translation: Moves the point by a specified distance in a particular direction.

Verifying the Coordinates of Point F

To verify the coordinates of point F again, follow these steps:

  1. Draw the Cartesian plane.
  2. Label the x- and y-axes with appropriate scales.
  3. Plot point F on the plane.
  4. Check that the point is in the Second Quadrant (Q2).
  5. Measure the distance from the origin to point F in the x- and y-directions.
