Question

another fossilized bone was found outside the area of the grid. the paleontologists need to extend the grid so they can record the location of the new bone. how can you move the trowel to the new point where the dinosaur bone is buried? move the trowel units ? , then ? units ? .

Explanation:

Step1: Identify the starting and ending points

The trowel is at \((0, 0)\) (the origin), and the new bone is at \((-3, -2)\). To get from \((0, 0)\) to \((-3, -2)\), we can first move horizontally (left/right) and then vertically (up/down), or vice versa.

Step2: Horizontal movement

Moving horizontally from \(x = 0\) to \(x=-3\) means moving 3 units to the left (since left is the negative x - direction).

Step3: Vertical movement

After moving horizontally, we move vertically from \(y = 0\) to \(y=-2\), which is 2 units down (since down is the negative y - direction). (Alternatively, we could move down 2 units first and then left 3 units.)

Answer:

Move the trowel \(3\) units left, then \(2\) units down (or move the trowel \(2\) units down, then \(3\) units left).
