Answer:
W(- 2, 3 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then
the coordinates of W' are 3 times the original coordinates.
Thus to find the pre- image divide the image coordinates by 3
W(- 6, 9 ) → W(- 6 ÷ 3, 9 ÷ 3 ) → W(- 2, 3 )
Answer:
A) W(-2, 3)
Step-by-step explanation:
A dilation is a geometric transformation that increases or decreases the original size of a shape by a scale factor. In this instance, the scale factor is three, and the coordinates of the image is W'(-6, 9). So, we need to calculate the coordinates of the original pre-image.
Basically, when we have the scale factor of a pre-image, we simply multiply it by it's original coordinates.
(-6)/3 = (-2)
9/3 = 3
W(-2, 3) would be our original coordinates prior to the scale factor of 3.
