Answer:
B is A reflected across the y-axis; only the signs of the x-coordinates of A and B are different.
Step-by-step explanation:
Consider the provided information.
It is given that positions of the coordinates of A and B :
From the origin, point A is 1 units to the left and 3.5 units down.
1 units left of the origin is the negative value of x i.e x = -1 and 3.5 units down origin is y = -3.5
Therefore, the coordinates of A is (-1, -3.5).
From the origin, point B is 1 units to the right and 3.5 units down.
1 units right of the origin is x = 1 and 3.5 units down origin is y = -3.5
Therefore, the coordinates of B is (1, -3.5).
We can see that x-coordinates of A and B are opposite in sign.
The reflection over y axis is gives us the opposite sign of x coordinate.
Therefore, B is A reflected across the y-axis; only the signs of the x-coordinates of A and B are different.
