Square abcd was translated using the rule (x, y) → (x – 4, y + 15)  to form a'b'c'd'. what are the coordinates of point d in the pre-image if the coordinates of point d’ in the image are (9, –8)? a) (13,  –23) b) (5, 7) c) (18, 1) d) (–6,  –4)

The translation is (x-4, y+15)

This means you would subtract 4 from the X coordinate and add 15 to the y coordinate.
 The original coordinates is (9,-8) 

The first number is X and the 2nd number is Y.

9-4 = 5

-8+15 = 7

The new location would be (5,7)

The answer is B.

8,400-6,400=xx/6,400anyways the percent increase is 31.25% or 0.3125 you can round if you can
