Math Problem Statement
Solution
The problem asks to find the distance from the point to the line given by the parametric equations:
Step 1: Identify the direction vector of the line.
From the parametric equations, the direction vector of the line is the coefficients of in each equation:
Step 2: Define the point on the line.
At , the point on the line is:
