Hello from MrBillDoesMath!

Answer:

Number marbles >= 5

Discussion:

Answer:

(-7.5, 3.5)

Step-by-step explanation:

$midpoint \: = ( \frac{x1 + x2}{2} \: , \: \frac{y1 + y2}{2} )$

$= ( \frac{ ( - 5) + ( - 10)}{2} , \frac{(5) + (2)}{2} )$

$= ( \frac{ - 15}{2} , \frac{7}{2} )$

$= ( - 7.5,3.5)$
