Answer:
The distance between x-coordinates of A and F is 3 units.The distance between y-coordinates of A and F is 1 unit. The coordinates of A' are (-8,4).
Step-by-step explanation:
The dilation rule is [tex]D_{F,3}(x,y)[/tex].
It means the center of dilation is F and scale factor is 3.
The coordinates of A are (-2,2) and the coordinates of F are (1,1).
The distance in the x-coordinates from A(–2, 2) to the center of dilation F(1, 1) is
[tex]-2-1=-3[/tex]
The distance can not be negative. So, the distance between x-coordinates of A and F is 3 units.
The distance in the y-coordinates from A(–2, 2) to the center of dilation F(1, 1) is
[tex]2-1=1[/tex]
The distance between y-coordinates of A and F is 1 unit.
According to given dilation rule,
[tex](x,y)\rightarrow (3(x-1)+1,3(y-1)+1)[/tex]
The coordinates of A' are
[tex]A(-2,2)\rightarrow A'(3(-2-1)+1,3(2-1)+1)[/tex]
[tex]A(-2,2)\rightarrow A'(3(-3)+1,3(1)+1)[/tex]
[tex]A(-2,2)\rightarrow A'(-8,4)[/tex]
Therefore the distance between x-coordinates of A and F is 3 units.The distance between y-coordinates of A and F is 1 unit. The coordinates of A' are (-8,4).
