hi,
If you have the co-ordinates of the reference line then 1. you can calculate the distance between the points.
2. keep y co-ordinate constant increase x xo-ordinate(which will be the next pixel) and again calculate distance. this distance should be same the distance calculated at starting point. make sure that the value is non-zero before calculating.
3. keep continuing for all rows

You can use hough transform to detect lines. Once lines are detected, you can use properties such as theta on the houghlines structure to filter your lines compared to a reference line.
Take a look at this example to see how to use hough transform to detect lines in MATLAB.
