Final answer:
The solution for y in the given inequality -x{10 > x > -10} is c. y = -x, as it directly states the relationship between y and x within the specified range.
Step-by-step explanation:
To solve for y given the inequality -x{10 > x > -10}, we need to clarify the notation used. Assuming the notation implies that y is equal to -x within the range of x being greater than -10 and less than 10, then the solution is simply c. y = -x. We do not need to perform any calculations since no specific value of x within the range was given, and the notation directly states the relationship between y and x.
Linear equations, which are of the form y = a + bx, represent straight lines on a coordinate plane. If b is negative, as in this case where b = -1 (since y = -x can be rewritten as y = 0 + (-1)x), this indicates that the line will slope downward to the right.
