Please help fast I have a exam

D. K'(-4, 8)

Step-by-step explanation:

Given the coordinate  (x,y), if this coordinate is dilated by a factor of k, the resulting coordinate will be expressed as (kx, ky). Note that each coordinate is multiplied by the scale factor.

Similarly considering the coordinate K(-1, 2). If this coordinate os dilated by a factor of 4, the resulting coordinate is expressed as;

K' = 4K

K' = 4(-1, 2)

K' = (4(-1), 4(2))

K' = (-4, 8)

Hence the coordinate of K' will be at (-4, 8)
