Answer to Problem 4.4MPS
The roads are not parallel.
Explanation of Solution
Given information: The given information is:
The points on highway
The points on highway
Calculation:
For two lines to be parallel, the slopes must be equal.
Since the slopes are
Since the slopes are not equal hence they are not parallel.
Therefore, the roads are not parallel.
