Given X = 3.5, Y = 2, Z = -0.3, how should the coordinates be written?

• A. (3.5, 2, -0.3)
• B. (2, 3.5, -0.3)
• C. (3.5, -0.3, 2)
• D. (-0.3, 3.5, 2)

Answer: (A)

In three-dimensional coordinates, values are written in the order X, Y, Z. Put X first, then Y, then Z. Since X = 3.5, Y = 2, and Z = -0.3, the correct notation is (3.5, 2, -0.3). Reordering the values would represent a different point in space, and placing the negative value in a different slot would also point to a different location.
