Question

Triangle WXY has vertices at W(8, 4), x(0, 8), and Y(4, 2). Triangle WXY will be dilated by a scale factor of 1. What will be the coordinates of W'?

Answer 1

We can describe the transformation from the original points to the scaled points as:

`P=(x,y)\longrightarrow P^(\prime)=(kx,ky)`

In this case, W=(8,4) and k=1/4.

Then, the scaled point is:

`W=(8,4)\longrightarrow W\text{'}=((1)/(4)\cdot8,(1)/(4)\cdot4)=(2,1)`

The coordinates of W' will be (2,1).

Option B is the answer.
