QUESTION
Find the equation of the line $5x+3y=15$ after a reflection in the line $y=x$
SOLUTION
SWAP THE VARIABLES AND YOU ARE DONE
$5y+3x=15$
PRACTICE QUESTIONS
Find the equation of the line after a reflection in the line $y=x$.
1. $4x+2y=21$
ANSWER: $2y+4x=21$
SOLUTION
Reflection in $y=x$ swaps $x$ and $y$.
$4x+2y=21$
Replace $x$ by $y$ and $y$ by $x$:
$4y+2x=21$
2. $5x-2y=100$
ANSWER: $-2y+5x=100$
SOLUTION
Reflection in $y=x$ swaps $x$ and $y$.
$5x-2y=100$
Replace $x$ by $y$ and $y$ by $x$:
$5y-2x=100$
3. $3x+7y=12$
ANSWER: $7y+3x=12$
SOLUTION
Reflection in $y=x$ swaps $x$ and $y$.
$3x+7y=12$
Replace $x$ by $y$ and $y$ by $x$:
$3y+7x=12$
4. $-2x+3y=8$
ANSWER: $3y-2x=8$
SOLUTION
Reflection in $y=x$ swaps $x$ and $y$.
$-2x+3y=8$
Replace $x$ by $y$ and $y$ by $x$:
$-2y+3x=8$
5. $6x-5y=30$
ANSWER: $-5y+6x=30$
SOLUTION
Reflection in $y=x$ swaps $x$ and $y$.
$6x-5y=30$
Replace $x$ by $y$ and $y$ by $x$:
$6y-5x=30$
6. $x+9y=-4$
ANSWER: $9y+x=-4$
SOLUTION
Reflection in $y=x$ swaps $x$ and $y$.
$x+9y=-4$
Replace $x$ by $y$ and $y$ by $x$:
$y+9x=-4$
