To find: The coordinates of the vertices after the reflection in the given axis of symmetry then graph the pre-image and the image.
Answer to Problem 25PPS
The coordinates of the vertices is
Explanation of Solution
Given:
The given vertices are
The vertices are reflected about the
Calculation:
Consider the vertices of the image is,
Multiply the vertex matrix by the matrix
Thus, the coordinate of the vertices of the image is
The graph for the image and the pre-image is shown in Figure 1
