Question

1. reflection across the x - axis

w(0, 2), f(1, 5), e(4, 3), r(3, 0)
w() f()e()r()

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ across the x - axis, the rule is $(x,y)\to(x, - y)$.

Step2: Apply rule to point W

For $W(0,2)$, using the rule $(x,y)\to(x, - y)$, we get $W'(0,- 2)$.

Step3: Apply rule to point F

For $F(1,5)$, using the rule $(x,y)\to(x, - y)$, we get $F'(1,-5)$.

Step4: Apply rule to point E

For $E(4,3)$, using the rule $(x,y)\to(x, - y)$, we get $E'(4,-3)$.

Step5: Apply rule to point R

For $R(3,0)$, using the rule $(x,y)\to(x, - y)$, we get $R'(3,0)$ since $-0 = 0$.

Answer:

$W'(0,-2),F'(1,-5),E'(4,-3),R'(3,0)$
