What do you think the answer is? Tell me and I will help you some more! :)
3x=129 , x =43 distribute 3 to get x by itself
45
50
You have to add 25 for each one so you get the answer
Bear in mind that for y intercept x=0 and for x intercept y=0
under a rotation about the origin of 180°
a point (x, y ) → (- x, - y )
hence D is correct, both the x and y coordinates of the points on ΔA'B'C' have opposite signs from the corresponding points on ΔABC
