  1. as you recall, reflection over the x-axis takes

    (x,y) -> (x,-y)

    So, just change the sign of all the y-values.

  2. A(1,4)=A(1,-4)
    B(3,-2)=b(3.2)
    D(4,2)=D(4,-2)
    jus inverse the sign daz all

  6. no it the right answer is 3,2 because we are using the coordinate plane method
