12 ft
Because if you start at ground level aka. 0 than go down 12 ft you would be at -12 than you go back up -12+12=0 than up 12 again 0+12=12 so you would be 12 ft above ground level

The answer to your question is: (8, -2)

Step-by-step explanation:

Data

A (9, -16)

L (7, 12)

Formula

$Xm = \frac{x1 + x2 }{2} Ym = \frac{y1 + y2}{2}$

Xm = $Xm = \frac{9 + 7}{2} Ym = \frac{-16 + 12}{2}$

Xm = 8 Ym = -2
