The parallelogram is reflected across the line y = x. Which of the following are coordinates of a vertex of the image?
Korvikt [17]

Answer:

A'(1,-5)

Step-by-step explanation:

The coordinates of the given quadrilaterals are

A(-5,1),B(-4,3),C(-2,1),D(-3,-1)


The reflection in the line y=x has the mapping,

(x,y)\rightarrow(y,x)


We just have to swap the coordinates.


This implies that,


A(-5,1)\rightarrow A'(1,-5)


B(-4,3)\rightarrow B'(3,-4)


C(-2,1)\rightarrow C'(1,-2)


D(-3,-1)\rightarrow D'(-1,-3)


Therefore the correct answer is A.

A'(1,-5)

SSSSS [86.1K]

fog(x)

\\ \rm\rightarrowtail \dfrac{(2/x+1)+3}{4/x+1)-1}

\\ \rm\rightarrowtail \dfrac{2+3x+3/x+1}{4-x-1/x+1}

\\ \rm\rightarrowtail \dfrac{3x+5}{3-x}

So

\\ \rm\rightarrowtail 3-x\neq 0

\\ \rm\rightarrowtail x\neq 3

Option h is correct
