Solve It! A contractor needs to build two straight roads, each passing through point A. One road must be parallel to Pine Street, and the other road must be perpendicular to Pine Street. Find the coordinates of a second point the parallel road will pass through and the coordinates of a third point the perpendicular road will pass through. Classify the coordinates below appropriately.
(10, 70)
(50, 40)
(60, 60)
On the parallel road
On the perpendicular road
On neither the parallel nor perpendicular road
