Any line parallel to L1 will have the same slope
+m%5B2%5D+=+m%5B1%5D+
+m%5B2%5D+=+-3%2F4+
The slope of L2 is +-3%2F4+
------------------------
Any line perpendicular to L1 will have slope
+m%5B3%5D+=+-1%2Fm%5B1%5D+
+m%5B3%5D+=+-1%2F%28%28+-3%2F4%29%29+
+m%5B3%5D+=+4%2F3+
The slope of L3 is +4%2F3+
