Answer:
The correct option is:
begin ordered pair 4 comma 12 end ordered pair i.e. (4,12).
Step-by-step explanation:
We are given the coordinates of the point A,B and C of the triangle ΔABC as:
A(-1,3) , B(2,1) and C(-2,-1).
Now it is given that there is dilation of this triangle about the origin with a scale factor of 4.
This means that the change in the coordinates after the transformation is given by the rule:
(x,y) → (4x,4y)
As A → A' , B → B' and C → C'
Hence the coordinates A',B' and C' are given by:
A' are (4×-1,4×3)=(-4,12)
B' are (4×2,4×1)=(8,4)
and C' are (4×-2,4×-1)=(-8,-4).
<em>Hence the coordinate point which is not a coordinate of dilation is:</em>
<em>begin ordered pair 4 comma 12 end ordered pair i.e. (4,12)</em>
