The location of the image of points <em>J </em>and <em>K </em>following a reflection across the x-axis are;
- J'(-3, -4), and K'(3, -4)
<h3>Which method can be used to find the image of a point following a reflection?</h3>
Coordinates of point are;
J(-3, 4), K(3, 4)
The given transformation is; A reflection across the x-axis
The representation of a reflection across the x-axis is presented as follows;
The image of <em>J </em>and <em>K </em>following a transformation across the x-axis are therefore;
