Question

  1. reflect across the x-axis

w ( , ) → w( , )
x ( , ) → x( , )
y ( , ) → y( , )
z ( , ) → z( , )

  1. rotate $90^{\circ}$ clockwise

a(2,4)
b(4,4)
c(5,1)
d(1,1)
a _____ b ___ c ___ d _____

Explanation:

Step1: Identify original coordinates (Q4)

W$(-2, 0)$, X$(1, -2)$, Y$(-2, -4)$, Z$(-5, -2)$

Step2: Reflect over x-axis (Q4)

Rule: $(x,y)\to(x,-y)$
W$(-2,0)\to$ W'$(-2, 0)$
X$(1,-2)\to$ X'$(1, 2)$
Y$(-2,-4)\to$ Y'$(-2, 4)$
Z$(-5,-2)\to$ Z'$(-5, 2)$

Step3: Confirm original coordinates (Q5)

A$(2,4)$, B$(4,4)$, C$(5,1)$, D$(1,1)$

Step4: Rotate 90° clockwise (Q5)

Rule: $(x,y)\to(y,-x)$
A$(2,4)\to$ A'$(4, -2)$
B$(4,4)\to$ B'$(4, -4)$
C$(5,1)\to$ C'$(1, -5)$
D$(1,1)\to$ D'$(1, -1)$

Answer:

Question 4:

W$(-2, 0)\to$ W'$(-2, 0)$
X$(1, -2)\to$ X'$(1, 2)$
Y$(-2, -4)\to$ Y'$(-2, 4)$
Z$(-5, -2)\to$ Z'$(-5, 2)$

Question 5:

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