Final answer:

The equation representing '9 less than x is -1' is x - 9 = -1. Solving for x, we find that x = 8.

Step-by-step explanation:

The equation that represents the statement '9 less than x is -1'. To translate this into a mathematical equation, we subtract 9 from 'x', which gives us the equation x - 9 = -1.

To find the value of x, we can rearrange the equation by adding 9 to both sides, which leads to x = -1 + 9. This simplifies to x = 8, which matches option c) x=8 from the given choices.
