Answer:
Coordinate of B' = (1, 5)
Step-by-step explanation:
If we reflect a point using X axis only Y coordinate gets changed, it changes its sign and X coordinate remains the same.
Here we need to reflect triangle ABC with A(3, -1), B(1, -5), and C(-2, -2) in the x-axis.
We need to find coordinate of B'.
So only Y coordinate changes sign, X remains the same.
Coordinate of B = (1, -5)
Coordinate of B' = (1, -5 x -1) = (1, 5)
Coordinate of B' = (1, 5)
