The Mid - point of the line segment is at coordinates -  M(- 7.5, 0.5)
We have two coordinate points -  A(- 10, 2)  and  B(- 5, -1)
We have to find the midpoint of this line AB.
<h3>What is Mid - Point Theorem?</h3>
It states that a line with endpoint coordinates as -  and
 and  has its mid - point at the coordinates -
 has its mid - point at the coordinates -

According to question, we have -
First coordinate Point -   = (- 10, 2)
 = (- 10, 2)
Second coordinate Point -  = (- 5, - 1)
 = (- 5, - 1)
Using the Mid - Point formula, we get -
 =
 =

Hence, the Mid - point of the line segment is at coordinates - 
 M(- 7.5, 0.5)

Answer:
4b² - 16
Step-by-step explanation:
The formula to find the area of a parallelogram equals  , where b = base and h - height. We're given the base as 2b + 4 and the height as 2b - 4.
, where b = base and h - height. We're given the base as 2b + 4 and the height as 2b - 4.
Therefore, the answer is 4b² - 16.
