Final answer:
To find the coordinates of the vertices for the glide reflection, reflect the given points over the line y = -2 and then translate them 3 units to the left.
Step-by-step explanation:
To find the coordinates of the vertices for the glide reflection, we need to apply the glide reflection transformation to the given points A(6, 4), B(3,8), and C(7,9).
Here's how we can do it:
1. Reflect the points A, B, and C over the line y = -2. This will give us A'(x, y), B'(x, y), and C'(x, y).
2. Translate A', B', and C' by 3 units to the left. This will give us the final coordinates for the vertices of the glide reflection.
By following these steps, we can find the coordinates of the vertices for the glide reflection.
