Answer 2

The complete statement is:

The sequence of transformations that maps $\triangle ABC$ onto $\triangle A'B'C'$ is a

reflection across the line x=-3 followed by a reflection across the line y=x

The coordinates of triangle ABC are:

A= (-4,4), B = (-8,2) and C = (-6,6)

First, the triangle is reflected across the line x = -3.

The rule of this transformation is:

$(x,y) \to (|x| - 6,y)$

When the above transformation is applied to $\triangle ABC$, the coordinates become:

$A = (-2,4)$

$B = (2,2)$

$C = (0,6)$

Next, reflect the above coordinates across the line y = x

The rule of this transformation is:

$(x,y) \to (y,x)$

When the above transformation is applied to $\triangle ABC$, the coordinates become:

$A' = (4,-2)$

$B' = (2,2)$

$C' = (6,0)$

Hence, the sequence of transformations that maps $\triangle ABC$ onto $\triangle A'B'C'$ is a reflection across the line x=-3 followed by a reflection across the line y=x
