Consider the relation y = - 8|x + 3| - 9. what are the coordinates of the vertex? (-3, 9) (-3, - 9) (3, - 9) (3, 9)

By simple substitution on the left side and on the right side of the given equation, we have to

For coordinates (-3,-9)

-9 = - 8|-3+3|-9

-9 = - 8|0|-9

-9=-9

Therefore, it is demonstrated that the coordinates of the vertex is

(-3,-9)
