Question

Which shows the coordinates of the image points for pre image points (x,y)?

Answer 1

C)
`(px,py)`

Explanation:

When we are dilating an image about the origin we need to multiply the scalar factor to each x and y co-ordinates of pre-image to get the co-ordinates of the transformed image.

Since scalar factor is
`p` , so we multiply the
`x` and
`y` with
`p`.

Pre-image
`(x,y)\rightarrow` Image
`(px,py)`

∴ Points of the image
`\rightarrow (px, py)`
