Quadrilateral abcd is reflected across the x-axis and then reflect across the y-axis to form quadrilateral a′b′c′d′. if the coordinates of vertex a are (-7, 3), what are the coordinates of vertex a′?
a.
(7, 3)
b.
(-7, -3)
c.
(7, -3)
d.
(-7, 3)
e.
(3, 7)

B(-7,-3)

Step-by-step explanation:

When you reflect across the x axis, your y coordinate is multiplied by -1.

(-7,-1(3))

(-7,-3)

The only answer choice that is the same as my result is B.(-7,-3).

b. x- 48 =120

step-by-step explanation:

b.-4 units

all you   do is count how many times you move
