Which point is reached by moving (4) units to the left from (-3) on the number line?

Answer and explanation

Correct answer: -(7) / (-7)

On a number line, moving to the left means moving in the negative direction. Each unit of leftward movement decreases the number by one. Starting at \\(-3\\) and moving four units left therefore means subtracting \\(4\\) from \\(-3\\), not adding it. This gives a point farther from zero on the negative side.

The calculation is \\(-3-4=-7\\). The four successive positions are \\(-4,-5,-6,-7\\), so the final point is \\(-7\\). Hence option A is correct. A common error is to use \\(-3+4=1\\), but adding four represents movement to the right, not to the left. The direction on the number line determines the sign of the change.
