Answer:
a+b=6
a-b =4
______subtract
(a-a)+(b-(-b))=6-4
0+2b = 2
b= 1
put the value of b at any equation
a+1 =6
then a=6-1=5
a square+b square= 25+1= 26

Step-by-step explanation:
Yreflection in y-axis (x, y) → (-x, y) **the sign of the x-coordinate changes, the y value stays the same**
A'(1, 4)
B'(5, 8)
C'(5, 4)
D'(4, 2)
