Right aabc has coordinates a(-7, 3), b(-7, 10), and c(-1,3). the triangle is reflected
over the x-axis and then reflected again over the y-axis to create aa'b'c'. which are
the coordinates of vertex a?

A'(7, - 3 )

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), thus

A(- 7, 3 ) → (- 7, - 3 )

Under a reflection in the y- axis

a point (x, y ) → (- x, y ), thus

(- 7, - 3 ) → A'(7, - 3 )
