Answer: B, (-3/2, -1)

Step-by-step explanation:

When you use the midpoint formula, (x1+x2/2 , y1+y2/2) you end up taking one away from -4, and dividing it by 2 (-3/2), and when you add 2 to -4, you get -2, divided by 2, is -1.

There are 620 students and 31 teachers at the Turner Middle School.There are 950 students and 38 teachers at the Green Middle Sc

We begin with the Turner Middle School:
Ratio of students to teachers: $\frac{620}{31}$
Green Middle School:
Ratio of students to teachers: $\frac{950}{38}$
Let check that we cannot form a proportion:
$\frac{620}{31}=20\text{ and } \frac{950}{38}=25$
The two ratios are not equals so we cannot form a proportion.
Let x be the number of teachers that Green have to hire in order to make the two ratios equal. We get the equation:
 $\frac{950}{38+x}=\frac{620}{31}\text{ and we solve the equation like this:}\\38+x=\frac{950\times31}{620}=47.5 \text{ and then:}\\x=47.5-38=9.5$

The Green school need to hire 9 teachers.

Part-to-whole ratio:
Turner Middle School:
$\frac{620}{31+620}$
Green Middle School:
$\frac{950}{38+950}$
