Dilation involves changing the size of a shape
The vertex of the image is (5,40)
How to determine the image
The vertex of the pre-image is given as:
(1,8)
The scale factor (k) is given as:
k = 5
So, the vertex of the image is:
Vertex = (1,8) * 5
This gives
Vertex = (5,40)
Hence, the vertex of the image is (5,40)
