For each exercise draw a grid and find the coordinates of the image point. 0 is the origin and $A$ is the point $(3,1) . R_{x}$ and $R_{y}$ are reflections in the $x$ - and $y$ -axes. $$ R_{y} \circ H_{O} :(1,-2) \rightarrow(\stackrel{?}{\longrightarrow}, \stackrel{?}{\longrightarrow}) $$

Key Concepts

Cartesian Coordinate System

The Cartesian coordinate system is a framework that allows every point in a plane to be expressed as an ordered pair (x, y), with x representing the horizontal position and y representing the vertical position. This system provides a basis for plotting points and performing geometric transformations.

Reflection Transformation

A reflection transformation creates a mirror image of a point or shape with respect to a specific line, such as the x-axis or y-axis. For a reflection across the y-axis, the sign of the x-coordinate is reversed while the y-coordinate remains unchanged.

Half-turn Transformation

A half-turn transformation, often represented as a 180-degree rotation about the origin, maps every point (x, y) to its diametrically opposite point (-x, -y). This operation effectively reverses both coordinates, producing a point directly opposite the original with respect to the origin.

Composition of Transformations

The composition of transformations involves applying multiple geometric operations in sequence. The order in which transformations are applied is crucial, as each transformation affects the coordinates of the points, and the final outcome results from the cumulative effect of all the individual operations.
