Which transformation would result in the area of a polygon being different from the area
of its pre-image?

a ) dilated by a scale factor of one

b) dilated by a scale factor of 2.5

c ) rotated 270° counterclockwise about the origin

d) translated four units up and two units to the right

B) Dilated by a scale factor of 2.5

Step-by-step explanation:

Dilation is multiplying the size of the polygon which would be changing the area. The reason A is wrong because multiplying anything by 1 doesn't change it.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
