The points are plotted and connected to make triangles
As per the diagram, the triangles are similar, each side of ABC is reduced twice to make the corresponding sides of DEF, so the scale factor is 1/2.

- They are similar by the definition of similarity in terms of a dilation.
From any proportion, we get another proportion by inverting the extremes (or the means):
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=
The corect answer is A. -3/2
or:
From any proportion, we get another proportion by inverting the extremes and the means:
We use a property of proportions:
so we have
3y = - 2x
