If a figure is dilated by scale factor of 3, what were the coordinates of the pre-image of W'(-6, 9) ? a. W(-18,27)
b. W(-3, 12)
c. W(-2,3)
d W(-9, 6)

We are given scale factor k=3. This means that each coordinate of a point is multiplied by 3 to get final point.

W' = 3*W

We can use this to find original point.

-6 = 3x

x = -2

9 = 3y

y = 3

So we have  

W(-2,3)

Step-by-step explanation:

Hope this is correct. If it is wrong please feel free to critique my mistake(s). I'm sorry in advance if it is incorrect.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
