Step-by-step Solution
To find point \( W \) on line segment \( \overline{UV} \) that is \( \frac{1}{7} \) of the distance from point \( U \) to point \( V \), we can use the concept of dividing a line segment in a given ratio.
Let the coordinates of points \( U \) and \( V \) be represented as follows:
- Let \( U = (x_U, y_U) \)
- Let \( V = (x_V, y_V) \)
The distance from \( U \) to \( V \) can be expressed as:
\[
\text{Distance} = \sqrt{(x_V - x_U)^2 + (y_V - y_U)^2}
\]
To find point \( W \) that is \( \frac{1}{7} \) of the distance from \( U \) to \( V \), we can use the section formula. The coordinates of point \( W \) can be calculated using the formula for dividing a line segment in the ratio \( m:n \), where \( m \) is the part from \( U \) and \( n \) is the part from \( V \).
In this case, we want \( W \) to be \( \frac{1}{7} \) of the way from \( U \) to \( V \). This means that the ratio \( m:n \) is \( 1:6 \) (since \( 1 + 6 = 7 \)).
Using the section formula, the coordinates of point \( W \) are given by:
\[
W = \left( \frac{mx_V + nx_U}{m+n}, \frac{my_V + ny_U}{m+n} \right)
\]
Substituting \( m = 1 \) and \( n = 6 \):
\[
W = \left( \frac{1 \cdot x_V + 6 \cdot x_U}{1 + 6}, \frac{1 \cdot y_V + 6 \cdot y_U}{1 + 6} \right)
\]
This simplifies to:
\[
W = \left( \frac{x_V + 6x_U}{7}, \frac{y_V + 6y_U}{7} \right)
\]
Thus, the coordinates of point \( W \) that is \( \frac{1}{7} \) of the distance from \( U \) to \( V \) are:
\[
W = \left( \frac{x_V + 6x_U}{7}, \frac{y_V + 6y_U}{7} \right)
\]
Quick Answer
The coordinates of point \( W \) are \( W = \left( \frac{x_V + 6x_U}{7}, \frac{y_V + 6y_U}{7} \right) \).
