Answer:

c = -6

d = 2

Explanation:

After reflection about the x-axis:

A --> A'

(2,3) --> (2,-3)

(4,3) --> (4,-3)

(2,6) --> (2,-6)

After translation:

(2 + c, -6 + d) --> (-4, -4)

2+c = -4

c = -6

-6+d = -4

d = 2

After translation by < c , d >, any point maps from (x , y) to:

< x , y > + < c , d >

< x+c , y+d >

c is the no. of units of horizontal movement:

+ve for right wards

-ve for left wards

d is the no. of units of vertical movement:

+ve for upwards

-ve for downwards
