Which transformation represents a dilation? \((1)(8,4) \rightarrow(11,7)\) \((3)(8,4) \rightarrow(-4,-8)\) \((2)(8,4) \rightarrow(-8,4)\) (4) \((8,4) \rightarrow(4,2)\)

Write an equation of the line of reflection that maps \(A(1,5)\) onto \(A^{\prime}(5,1)\).

The coordinates of the vertices of \(\triangle A B C\) are \(A(2,-3), B(0,4)\) and \(C(-1,5)\). If the image of point \(A\) under a translation is point \(A^{\prime}(0,0)\), find the images of points \(B\) and \(C\) under this translation.

Graph \(\triangle A B C\) with coordinates \(A(1,3), B(5,7)\), and \(C(8,-3)\) On the same set of axes, graph \(\triangle A^{\prime} B^{\prime} C^{\prime}\), the reflection of \(\triangle A B C\) in the \(y\)-axis.
