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)?

(13,-23)

Step-by-step explanation:

A sqaure ABCD was translated using the rule (x,y→(x-4,y+15) to form A'B'C'D'. Now the coordinates of point D in the iamge are (9,-8) therefore pre image of point D is

(by using property when a number go form left to right side then sign changes of a number)

( by using property of addition)

similarly, we find value of y

hence, the coordinate of D in pre iamge is (13,-23).

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
