Answer 2

Answer:

From the given figure:

Labelled the triangle as A, B and C.

Coordinates of triangle are:

A(-3, -2) , B(-7, -3) and C(-4, -5)

The rule of dilation with scale factor k = 3 and centered at (-7, -6) is:

$(x, y) \rightarrow (3(x+7)-7, 3(y+6)-6)$

or

$(x, y) \rightarrow (3x + 14, 3y+12)$

Now, find the dilated image of the given figure:

$A(-3, -2) \rightarrow (3(-3)+ 14, 3(-2)+12) =A'(5, 6)$

$B(-7, -3) \rightarrow (3(-7)+ 14, 3(-3)+12) =B'(-7, 3)$

$C(-4, -5) \rightarrow (3(-4)+ 14, 3(-5)+12) =C'(2, -3)$

You can see the graph of the dilated figure as shown below.
