Textbook Question
Find the midpoint of each line segment with the given endpoints. (8, 3√5) and (−6, 7√5)
Verified step by step guidance1
Recall that the midpoint \( M \) of a line segment with endpoints \( (x_1, y_1) \) and \( (x_2, y_2) \) is given by the formula:
\[ M = \left( \frac{ x_1 + x_2 }{ 2 }, \frac{ y_1 + y_2 }{ 2 } \right) \]
Identify the coordinates of the given endpoints:
\( (x_1, y_1) = (8, 3\sqrt{5}) \) and \( (x_2, y_2) = (-6, 7\sqrt{5}) \).
Calculate the midpoint's \( x \)-coordinate by adding the \( x \)-values and dividing by 2:
\[ \frac{8 + (-6)}{2} \]
Calculate the midpoint's \( y \)-coordinate by adding the \( y \)-values and dividing by 2:
\[ \frac{3\sqrt{5} + 7\sqrt{5}}{2} \]
Combine the results to write the midpoint as:
\[ \left( \frac{8 + (-6)}{2}, \frac{3\sqrt{5} + 7\sqrt{5}}{2} \right) \]

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Midpoint Formula
The midpoint formula calculates the point exactly halfway between two given points in a coordinate plane. It is found by averaging the x-coordinates and the y-coordinates separately: Midpoint = ((x₁ + x₂)/2, (y₁ + y₂)/2). This formula helps locate the center of a line segment.
