Answer:

Explanation:

To find the coordinates of Mary's new apartment, she needs to be located midway between her home and her school. The midpoint formula for two points

(

1

,

1

)

(x

1

,y

1

) and

(

2

,

2

)

(x

2

,y

2

) is given by:

Midpoint

=

(

1

+

2

2

,

1

+

2

2

)

Midpoint=(

2

x

1

+x

2

,

2

y

1

+y

2

)

In this case, her home coordinates are

(

28

,

10

)

(−28,−10) and her school coordinates are

(

4

,

3

)

(4,3). Applying the midpoint formula:

Midpoint

=

(

28

+

4

2

,

10

+

3

2

)

Midpoint=(

2

−28+4

,

2

−10+3

)

Midpoint

=

(

12

,

3.5

)

Midpoint=(−12,−3.5)

So, the coordinates of her new apartment are

(

12

,

3.5

)

(−12,−3.5), which is closest to option C.
