Square RSTU is translated to form R'S'T'U', which has vertices R'(–8, 1), S'(–4, 1), T'(–4, –3), and U'(–8, –3). If point S has coordinates of (3, –5), which point lies on a side of the pre-image, square RSTU?

Verified Answer :

 The options of the question are the points

\(A(-5,-3)\\B(3,-3)\\C(-1,-6)\\D(4,-9)\)

Step 1

Find the rule of the translation of the pre-image to the image

we know that

the point S has coordinates of \((3,-5)\)

the point S' has coordinates of  \((-4,1)\)

so

a) the rule of the translation of the pre-image to the image is

\((x.y)----> (x-7,y+6)\)

that means

the translation is \(7\) units to the left and \(6\) units up

Step 2

Find the inverse rule of the translation of the image to the pre-image

a) the inverse rule of the translation of the image to the pre-image is

\((x',y')---> (x'+7,y'-6)\)  

that means

the translation is \(7\) units to the right and \(6\) units down

Step 3

Find the coordinates of the vertices of the pre-image

Applying the inverse rule of the translation of the image to the pre-image

a) Point \(R'(-8,1)\)

\((x',y')---> (x'+7,y'-6)\)  

\(R'(-8,1)---> R(-8+7,1-6)\)  

\(R'(-8,1)---> R(-1,-5)\)  

b) Point \(T'(-4,-3)\)

\((x',y')---> (x'+7,y'-6)\)  

\(T'(-4,-3)---> T(-4+7,-3-6)\)  

\(T'(-4,-3)---> T(3,-9)\)  

c) Point  \(U'(-8,-3)\)

\((x',y')---> (x'+7,y'-6)\)  

\(U'(-8,-3)---> U(-8+7,-3-6)\)  

\(U'(-8,-3)---> U(-1,-9)\)  

Step 4

Using a graphing tool

graph the points of the pre-image and the points A,B,C and D to determine the solution of the problem

we have

\(R(-1,-5)\\S(3,-5)\\T(3,-9)\\U(-1,-9)\)

\(A(-5,-3)\\B(3,-3)\\C(-1,-6)\\D(4,-9)\)

see the attached figure        

therefore        

the answer is

\(C(-1,-6)\)
