Step-by-step Solution
To find point \( C \) on line segment \( \overline{AB} \) that is \( \frac{1}{5} \) of the distance from \( A \) to \( B \), we can use the concept of dividing a line segment in a given ratio.
Let's denote the coordinates of points \( A \) and \( B \) as follows:
- Let \( A = (x_A, y_A) \)
- Let \( B = (x_B, y_B) \)
The distance from \( A \) to \( B \) can be represented as a vector:
\[
\overrightarrow{AB} = (x_B - x_A, y_B - y_A)
\]
To find point \( C \), which is \( \frac{1}{5} \) of the way from \( A \) to \( B \), we can calculate the coordinates of \( C \) using the formula for dividing a segment in a given ratio. Since \( C \) is \( \frac{1}{5} \) of the way from \( A \) to \( B \), we can express the coordinates of \( C \) as:
\[
C = A + \frac{1}{5} \overrightarrow{AB}
\]
Substituting the vector \( \overrightarrow{AB} \):
\[
C = A + \frac{1}{5} (B - A)
\]
\[
C = A + \frac{1}{5} (x_B - x_A, y_B - y_A)
\]
\[
C = (x_A, y_A) + \left(\frac{1}{5}(x_B - x_A), \frac{1}{5}(y_B - y_A)\right)
\]
\[
C = \left(x_A + \frac{1}{5}(x_B - x_A), y_A + \frac{1}{5}(y_B - y_A)\right)
\]
Thus, the coordinates of point \( C \) are:
\[
C = \left(x_A + \frac{1}{5}(x_B - x_A), y_A + \frac{1}{5}(y_B - y_A)\right)
\]
This gives you the exact position of point \( C \) on the line segment \( \overline{AB} \) that is \( \frac{1}{5} \) of the distance from \( A \) to \( B \).
Quick Answer
The coordinates of point \( C \) are \( C = \left(x_A + \frac{1}{5}(x_B - x_A), y_A + \frac{1}{5}(y_B - y_A)\right) \).
