So since the triangle is being reflected across the x-axis we have to we use the reflection formula for reflecting across the x-axis which is (x,y) to (x,-y) meaning that T(-3,-2) becomes (-3,2), and R (6,2) becomes (6,-2) and S (-1, -6) becomes (-1,6) , Hope this helps
The rule is (x,y)➡️ (x,-y)
The other answers are above
