Which choice correctly describes the dilation shown here?

Reduction by scale factor 2 5 \frac{2}{5} 5 2

Enlargement by scale factor 2 5 \frac{2}{5} 5 2

Enlargement by scale factor 2.5

Find the coordinates of the image of the triangle after a dilation with scale factor k = - 2.

A ′ ( − 2 , − 6 ) , B ′ ( 4 , − 2 ) , C ′ ( − 8 , − 4 ) A'\left(-2,-6\right),\ B'\left(4,\ -2\right),\ C'\left(-8,-4\right) A ′ ( − 2 , − 6 ) , B ′ ( 4 , − 2 ) , C ′ ( − 8 , − 4 )

A ′ ( − 6 , − 2 ) , B ′ ( − 2 , 4 ) , C ′ ( − 4 , − 8 ) A'\left(-6,-2\right),\ B'\left(-2,\ 4\right),\ C'\left(-4,-8\right) A ′ ( − 6 , − 2 ) , B ′ ( − 2 , 4 ) , C ′ ( − 4 , − 8 )

A ′ ( − 1 2 , − 3 2 ) , B ′ ( 1 , − 1 2 ) , C ′ ( − 2 , − 1 ) A'\left(-\frac{1}{2},-\frac{3}{2}\right),\ B'\left(1,\ -\frac{1}{2}\right),\ C'\left(-2,-1\right) A ′ ( − 2 1 , − 2 3 ) , B ′ ( 1 , − 2 1 ) , C ′ ( − 2 , − 1 )

A ′ ( − 3 2 , − 1 2 ) , B ′ ( − 1 2 , 1 ) , C ′ ( − 1 , − 2 ) A'\left(-\frac{3}{2},-\frac{1}{2}\right),\ B'\left(-\frac{1}{2},1\right),\ C'\left(-1,-2\right) A ′ ( − 2 3 , − 2 1 ) , B ′ ( − 2 1 , 1 ) , C ′ ( − 1 , − 2 )

A scale factor of less than one means

That the image will be a reduction of the pre-image.

that the image will be larger than the pre-image.

That the image will be the same as the pre-image.

That you need to subtract that amount off of each side.
