Answer:
(1, - 3 )
Step-by-step explanation:
Using the translation rule (x, y ) → (x + 2, y + 1 ), then
B(- 1, 2 ) → (- 1 + 2, 2 + 1) → (1, 3 )
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(1, 3 ) → (1, - 3 )
Answer: its the first one "opposite sides with equal length"
X=-0.9375 or -15/16
-0.6+0.9=x+2.4
-0.6x-x=2.4-0.9
-1.6x=1.5
x= -0.9375
