  2. A train starts 95 miles away. A train starts 63 miles away. Every minute it gets 5 miles further away. When will the trains be the same distance away? Every minute it gets 9 miles further away. 9 example one. 5 slope X means slope X means minute minute +63 +95 Y int Y means Y int Y means miles miles equation y = 9x + 63 equation y = 5x + 95 5x + 95 = 9x + 63 -63 -63 5x + 32 = 9x 8 minutes -5x -5x 32 = 4x 8 = x
