1. Problem Description
We are given two lines. Line passes through the points and . Line passes through the points and . We need to determine if line is parallel to line , and explain why or why not.
2. Solution Steps
Two lines are parallel if and only if their slopes are equal. Thus, we need to find the slope of each line and compare them.
The slope of a line passing through points and is given by the formula:
For line , the points are and . Let and .
Then the slope of line is:
For line , the points are and . Let and .
Then the slope of line is:
Since and , we have . Therefore, the lines are parallel.
3. Final Answer
Yes. The lines have the same slope.
