Question

the missing parts in the photo for answer B and D are "B-. F(-4,-4)". "D-. F(-1,-1)

Answer 1

The coordinates of D' = (-4,6)

The coordinates of E' = (4,2)

The coordinates of F' = (-2,-2)

Since triangle D'E'F' is the result of dilating triangle DEF with a scale factor of 2

then dilating triangle D'E'F' with a scale factor of 1 / 2 should give us triangle DEF.

Hence,

`\begin{gathered} D=(1)/(2)(-4,6)=(-2,3) \\ E=(1)/(2)(4,2)=(2,1) \\ F=(1)/(2)(-2,-2)=(-1,-1) \end{gathered}`
