Question

the number line shows an unknown number, z. is z - 1 positive or negative? positive negative

Explanation:

Step1: Analyze the position of z

From the number - line, we can see that \(z<-1\).

Step2: Subtract 1 from z

If \(z < - 1\), then \(z-1< - 1-1\).

Step3: Calculate the result

\(z - 1<-2\). Since \(z - 1\) is less than 0, it is negative.

Answer:

negative
