Question

1. reflection across the x - axis

u(4, 2), v(2, 4), n(5, 4)
u( ) v( ) n( )

Explanation:

Step1: Recall reflection rule

The rule for reflecting a point $(x,y)$ across the $x - axis$ is $(x,-y)$.

Step2: Find $U'$

For point $U(4,2)$, applying the rule, we get $U'(4,- 2)$.

Step3: Find $V'$

For point $V(2,4)$, applying the rule, we get $V'(2,-4)$.

Step4: Find $N'$

For point $N(5,4)$, applying the rule, we get $N'(5,-4)$.

Answer:

$U'(4,-2)$, $V'(2,-4)$, $N'(5,-4)$
