What is the midpoint of the segment shown below

(-1, -1/2)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates and divide by 2

( -11+9)/2 = -2/2 = -1

To find the y coordinate of the midpoint, add the y coordinates and divide by 2

(0+-1)/2 = -1/2

(-1, -1/2)

350 months.

Step-by-step explanation:

$72,912 - $2,912 = $70,000

$70,000 ÷ $200 = 350 months
