# Find the midpoint of the line segment joining the points P1 and P2 .${P}_{1}=\left(-4,-3\right);{P}_{2}=\left(2,2\right)$

The midpoint of line segment is $\left(-1,-\frac{1}{2}\right)$.

See the step by step solution

## Step 1. Given information.

Find the midpoint of the line segment joining the points P1 and P2 .

${P}_{1}=\left(-4,-3\right);{P}_{2}=\left(2,2\right)$

## Step 2. Midpoint Formula.

The midpoint $M=\left(x,y\right)$of the line segment from ${P}_{1}=\left({x}_{1},{y}_{1}\right)\mathrm{to}{P}_{2}=\left({x}_{2},{y}_{2}\right)$is

$M=\left(x,y\right)=\left(\frac{{x}_{1}+{x}_{2}}{2},\frac{{y}_{2}+{y}_{1}}{2}\right)$

## Step 3. Apply the midpoint formula.

The coordinates (x, y) of the midpoint M are

$x=\frac{{x}_{1}+{x}_{2}}{2}=\frac{-4+2}{2}=-1\mathrm{and}y=\frac{{y}_{1}+{y}_{2}}{2}=\frac{-3+2}{2}=-\frac{1}{2}$

So, Midpoint $M=\left(x,y\right)=\left(-1,-\frac{1}{2}\right)$

## Step 4. Conclusion.

The midpoint of the line segment is $\left(-1,-\frac{1}{2}\right)$.
