Answer:

First, we need to know the formula when a scale factor appears:

New coordinate =  (scale factor)*(old coordinate)

So using this formula we have:

1) c' = (-2,1)*2/3  

  c' = (-4/3,2/3)

2) r = (-5,2)*2/3

   r = (-10/3,4/3)

3) a = (-6,7)*2/3

   a = (-4,14/3)

4) f = (-3,9)*2/3

   f = (-2,6)

5) t = (-1,6)*2/3

   t = (-2/3,4)

Answer:

560 ants and non linear function

Step-by-step explanation:

12 months divided by 3 months is 4. 35 times 2 is 70. Again is 140. Again is 280. Again a 4th time is 560 ants. It is not linear because it does not increase the same amount each time.
