Question

find the boat! use integer coordinates in the table, then press fire! press reset to try another pair of coordinates. (we recommend taking turns with your classmate.) keep firing until youve found the entire boat. youve made 0 attempts.

Explanation:

Step1: Analyze the grid

The grid has x - coordinates (vertical axis) from 0 to 3 and y - coordinates (horizontal axis) from 0 to 3. We need to find the coordinates of the boat (the dots). Let's list the coordinates of the dots:

• For x = 1, y = 1; x = 1, y = 2; x = 1, y = 3
• For x = 2, y = 1; x = 2, y = 2; x = 2, y = 3
• For x = 3, y = 1; x = 3, y = 2; x = 3, y = 3

Wait, no, looking at the grid, the dots are at (1,1), (1,2), (1,3), (2,1), (2,2), (2,3), (3,1), (3,2), (3,3)? No, maybe I misread. Wait, the x - axis is vertical (labeled x) with values 0,1,2,3 and y - axis is horizontal (labeled y) with values 0,1,2,3. The dots:

• When x = 1 (vertical line x = 1), y = 1,2,3? Wait, no, the first row (x = 0) has y = 1,2,3? No, the grid: the top - most horizontal line is y - axis with y = 0,1,2,3? Wait, maybe the coordinates are (x,y) where x is the vertical coordinate (rows) and y is the horizontal coordinate (columns). Let's re - examine:

Looking at the grid, the points (dots) are:

• (1,1), (1,2), (1,3)
• (2,1), (2,2), (2,3)
• (3,1), (3,2), (3,3)

Wait, no, maybe the boat is a line. Wait, the problem says "Find the boat!". Maybe the boat is a set of connected points. Let's check the coordinates:
Looking at the grid, the dots are at (1,1), (2,1), (3,1) (vertical line x = 1,2,3 and y = 1)? No, no, the x - axis is vertical (so x = 0 is the left - most vertical line, x = 1 next, etc.), y - axis is horizontal (y = 0 is the bottom - most horizontal line, y = 1 next, etc.). Wait, the dots:

• At x = 1 (vertical line x = 1), y = 1,2,3 (three dots)
• At x = 2 (vertical line x = 2), y = 1,2,3 (three dots)
• At x = 3 (vertical line x = 3), y = 1,2,3 (three dots)

Wait, maybe the boat is a 3x3 square? No, maybe I made a mistake. Wait, the problem is to use integer coordinates. Let's pick a coordinate, say (1,1). Let's check:
If we enter x = 1 and y = 1, then press "Fire!".

Step2: Select a coordinate

Let's choose one of the dot coordinates. For example, (1,1). So in the table, we put x = 1 and y = 1.

Answer:

One possible coordinate of the boat is (1,1) (other possible coordinates include (1,2), (1,3), (2,1), (2,2), (2,3), (3,1), (3,2), (3,3) as these are the dot positions in the grid).
