Question

20.Dilate Point B by a scale factor of 1/2Va) (1.5,-4)c) (-1,-1.5)b) (-1.5,1)d) (-2,-2)

Answer 1

the coordinate of point B is (-3,2)

In order to dilate the point with a scale factor of 1/2 we need to multiplicate the scale factor by the coordinate-x and the coordinate-y

coordinate x

`-3\cdot(1)/(2)=-1.5`

coordinate y

`2\cdot(1)/(2)=1`

the coordinate dilate is

B'(-1.5,1)

the correct answer is b
