Answer 1

Explanation:

see the figure below

let's start from bottom left point

we have to calculate position from P to that point as below

it is 2 units up and 11 units left

so as scale factor is 1/2

we have to shift that point to 1 unit up and 5.5 units left

pink point corresponding to it is denoted below

we have to do the same process for all the five points to cover the total figure
