What is the midpoint of (2, -3) and (4, 1)
daser333 [38]

Answer:

The answer is

<h2>( 3 , - 1)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )\\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(2, -3) and (4, 1)

The midpoint is

M = ( \frac{2 + 4}{2}   \: , \:  \frac{ - 3 + 1}{2} ) \\  = ( \frac{6}{2}  \: , \:  -  \frac{2}{2} )

We have the final answer as

<h3>( 3 , - 1)</h3>

Hope this helps you
