The coordinates of point P is (-4 , 2) and the coordinates of point T is (4 , -3)

So, we will check which translation is true:

1) reflection over y axis then reflection over x axis

so, (-4,2) to (4,2) then (4, -2)

This option is wrong

2) translation 1 unit to the right then rotation 180 degrees

so, (-4, 2) to (-3, 2) then (3, -2)

This option is wrong

3) reflection over y axis then rotation 270 conterclockwise

So, (-4,2) to (4,2) then (-2, 4)

This option is wrong

4) translation 1 unit up, 8 units to the right then reflection over x-axis

(-4,2) to (-4, 3) to (4, 3) then (4, -3) which is equal to the point T

This option is true

So, the answer is the last option
