To represent the expression 2(-4) on a number line, we need to understand that multiplying a number by a negative value will make it go in the opposite direction on the number line.
So, we start at zero on the number line. The number 2 tells us that we need to take 2 steps, but the negative sign (-) tells us to take those steps in the opposite direction.
Since the number is -4, we take 2 steps to the left on the number line. Each step is 1 unit, so we move 2 units to the left.
Starting from zero, we move 1 unit to the left, and then another 1 unit to the left. Counting backwards, we end up at the number -2.
Therefore, the expression 2(-4) on the number line is represented by the point -2. But, we have to remember that multiplying a positive number by a negative number gives us a negative result. So, the final answer is -8.
