Question

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

Answer 1

Answer:

C) $(px,py)$

Step-by-step 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 $\rightarrow (px, py)$
