Please guys help me please

lbvjy [14]

Answer:

$C' = (2,8)$

$A' = (4,4)$

$T' =(10,10)$

Step-by-step explanation:

Given

$k =2$

$C =(1,4)$

$A = (2,2)$

$T =(5,5)$

Solving (a): The new points

To do this, we simply multiply the old points by the scale factor.

i.e.

$New = Old * k$

So:

$C' = (1,4) * 2 = (2,8)$

$A' = (2,2) * 2 = (4,4)$

$T' = (5,5) * 2 = (10,10)$

Solving (b): The graph of the original image
