I dont know what dilated means but here is the question:

 

Triangle \(ABC\) with vertices at \(A(1,1)\), \(B(1,-2)\) and \(C(5,-2)\) is translated up 3 units and then dilated with respect to the origin by a factor of 2. What are the new coordinates of point \(C\)? Express your answer as an ordered pair.

dilated means enlarged. 

When the pupils of your eyes dilate, they get bigger :)

 

C(5,-2)

translatated up three

C'(5,1)

 

This is 5 units to the right and 1 unit up from the origin

If I dilate it wrt the origin with a factor of 2 then

it will be 10 units to the right and 2 units up so

C"(10,2)
