I really need help with parts B, C, and D. I think I did part A right but would like that looked over to be sure.

The Marching Band Question A Marching Band Direction is designing the steps the band will take this year during their half time performance. He places band members along the lines of the shape below on the coordinate graph so he can easily determine the translations of the object. Part A: The director wants to be sure that both sides are a mirror image. What should each the points be if the shape was reflected across the y-axis? Explain your work. (-20, 10) (-10, -10] (2, - 18) When the points ( X, y) are reflected over the y-axis it becomes ( -4 , 4 ) Point A : ( 2, (2) Point B: (20, 10 ) Point c: ( 10, - 10 )_ PointD: ( 2 , - 18 ) Part B: The director wants the next formation to appear like the bat is flying so he decides to perform a translation 12 units down and 6 units to the right. What are the new coordinates of Point B and Point C? Explain your work. Point B': Point C': Part C: Next, the director wants to formation to rotate 90" counter clockwise about the origin. What are the new coordinates of Point A and Point D? Explain your work. Point A': Point D' Part D: Finally, the director wants to dilate the formation by a scale factor of - about the origin. What are the new coordinates of Points A and Point C? Show and explain your work Point A': Point C'
