Final answer:
To list the numbers -6, 0, 8, -9 from least to greatest, order them based on their position on the number line relative to zero: -9, -6, 0, 8.
Step-by-step explanation:
When asked to list numbers from least to greatest, this requires an understanding of the number line and the value of integers. Negative numbers are less than zero, so they are considered less than any positive number. T
o order the given numbers -6, 0, 8, -9 from least to greatest, we will start with the smallest (most negative) number and move towards the largest (most positive) number.
The correct order from least to greatest is -9, -6, 0, 8. To reach this answer, we note that both -9 and -6 are negative, with -9 being smaller because it is further from zero on the number line, followed by -6, which is closer to zero but still negative. Zero itself is neither negative nor positive, and it is the next largest after -6. Finally, 8 is a positive number and greater than zero, making it the largest number in this set.
