Beau Gonzales · Answer 1

B (-7,-3). Because it went from the 2 quadrant over to the 3 quadrant (it reflected over the x axis) and then to the 4 quadrant (it reflect over the y axis)

Ann Goodman · Answer 2

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).
