Can someone !
15.) part b:
after triangle 2 is translated, it is reflected across the y-axis and then across the x-axis. what are the coordinates after each reflection?

1 >2
reflection across y axes, and then translate to the right 3 units

if triangle 2 translated up 4 units (add 4 to y coordinate), five units left (-5 from x-coordinate)
(8-5,-13+4) > (3,-9)
(4-5, -1+4)> (-1, 3)
(13-5,-1+4)>(8,3)

Part 2.
reflected across y,  x coordinate change to the opposite
(3,-9)>(-3, -9)
(-1,3)>(1, 3)
(8,3)> (-8,3)
reflected across x,  y coordinate change to the opposite
(-3, -9)>(3, -9)
(1, 3)>(-1,3)
 (-8,3)>(8,-3)

The answer is 1 because you have to flip the sign when dividing by negative number and 3
