Question

Find the coordinates of the midpoint of the segment with the given endpoints.

$\mathbf{(}\mathbf{-}\mathbf{3}\mathbf{,}\mathbf{4}\mathbf{)}\mathbf{,}\mathbf{(}\mathbf{-}\mathbf{2}\mathbf{,}\mathbf{-}\mathbf{3}\mathbf{)}$

Short answer

The coordinates of the midpoint of the segment with the given endpoints is$\left(-\frac{{\displaystyle 5}}{{\displaystyle 2}},\frac{{\displaystyle 1}}{{\displaystyle 2}}\right)$.

Step-by-step solution

Step 1. State the concept of ‘midpoint of a segment in 2 dimensional plane’.

Let the two points in 2 dimensional plane be $(x_1,y_1)$and $(x_2,y_2)$.

The midpoint of the segment with endpoints is given as:

$(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\dots \left(1\right)$

Where $(x,y)$is the midpoint.

Step 2. Calculate the distance.

The two points which is given are $(-3,4)$and $(-2,-3)$.

Substitute $(-3,4)$as $(x_1,y_1)$and $(-2,-3)$as $(x_2,y_2)$in $\left(1\right)$to calculate the distance.

Step 3. State the conclusion.

Therefore, midpoint of the segment with the endpoints$(-3,4)$ and $(-2,-3)$is $\left(-\frac{{\displaystyle 5}}{{\displaystyle 2}},\frac{{\displaystyle 1}}{{\displaystyle 2}}\right)$.
