(9,1) and (2,9)
Transcript text: Find the midpoint of the segment with the following endpoints.
\[
(9,1) \text { and }(2,9)
\]
Solution
Solution Steps
To find the midpoint of a line segment with given endpoints, you can use the midpoint formula. The midpoint \((M)\) of a segment with endpoints \((x_1, y_1)\) and \((x_2, y_2)\) is given by:
\[
M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)
\]
Solution Approach
Identify the coordinates of the endpoints.
Apply the midpoint formula to calculate the midpoint.
Step 1: Identify the Coordinates of the Endpoints
Given endpoints are:
\[
(9, 1) \text{ and } (2, 9)
\]
Step 2: Apply the Midpoint Formula
The midpoint \( M \) of a segment with endpoints \((x_1, y_1)\) and \((x_2, y_2)\) is given by:
\[
M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)
\]
Step 3: Calculate the Midpoint
Substitute the given coordinates into the midpoint formula:
\[
M = \left( \frac{9 + 2}{2}, \frac{1 + 9}{2} \right)
\]
\[
M = \left( \frac{11}{2}, \frac{10}{2} \right)
\]
\[
M = \left( 5.5, 5.0 \right)
\]
