Question

Suppose WZ is on a coordinate plane located at w(-3,5) and Z(1,1).Under a dilation centered at the origin, wz becomes W'Z' withcoordinates W'(-12,20) and Z'(4,4). What is the scale factor for thisdilatione

Answer 1

Let's begin by listing out the information given to us:

$\begin{gathered} W\mleft(-3,5\mright),Z\mleft(1,1\mright) \\ W^{\prime}\mleft(-12,20\mright),Z^{\prime}\mleft(4,4\mright) \end{gathered}$

We will proceed to calculate the difference between the pre-image & the image. We have:

$undefined$
