Question

1. reflection across the line y = x. b(-2, 1), s(-2, 2), r(3, 3), j(2, -2) b ( ) s( ) r( ) j( )

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ across the line $y = x$, the coordinates are swapped, so the new point is $(y,x)$.

Step2: Reflect point B

For $B(-2,1)$, swapping coordinates gives $B'(1, - 2)$.

Step3: Reflect point S

For $S(-2,2)$, swapping coordinates gives $S'(2,-2)$.

Step4: Reflect point R

For $R(3,3)$, swapping coordinates gives $R'(3,3)$.

Step5: Reflect point J

For $J(2,-2)$, swapping coordinates gives $J'(-2,2)$.

Answer:

$B'(1, - 2)$, $S'(2,-2)$, $R'(3,3)$, $J'(-2,2)$
