Answer:
(x,y) maps to (-y,x).
Step-by-step explanation:
Use vertex I as an example.
Pre-image I is graphed at point (-3,2), while image I' is graphed at point (-2,-3) .
In order to change between these points, the x and y coordinates must be swapped, as well as multiplying the y coordinate by -1.
The answer is B. Plug in the x values to check the y values.
You would take 9x3 and get 27 and then add that to 21 which is 48 and then divide 48 by 3 and get 16 so 16in each case
So if you find the length of 2 of the sides then you find the length of the other two, so now you have all the side lengths. You add all the lengths up and then you have your perimeter.
