Find the midpoint of the line segment joining the points (-2,-2) and (-4,9).

11Alexandr11 [23.1K]

Answer:

The answer is

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,-2) and (-4,9).

The midpoint is

$M = ( \frac{ - 2 - 4}{2} \: , \: \frac{ - 2 + 9}{2} ) \\ = ( - \frac{6}{2} \: , \: \frac{7}{2} )$

We have the final answer as

$( - 3 \: , \: \frac{7}{2} )$

Well, the number should be 2,222 since she wants the hundreds place to be a 2, being worth 200. Since she wanted all the digits to have the same number, it would be 2,222 for your final answer.

Hope this helped!
