Across, Then Up: Captain Mia's Treasure Map

Ahoy! On Treasure Beach, Captain Mia has a treasure map with a grid of lines. Instead of naming squares, her map marks points where the lines cross, with two numbers like (3, 5).

Remember: Every grid starts at the bottom-left corner, the point (0, 0), called the origin. In a point like (3, 5), the first number says how far to go across, and the second number says how far to go up. So (3, 5) means 3 across, then 5 up.

Magic trick: Walk along the hall, then up the stairs! Always go across first, then up.
