Question

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

Explanation:

Step1: Analyze the number line

From the number line, the unknown number \( t \) is at the position of \( 1 \)? Wait, no, looking at the number line, the red dot is at \( t \), and below it, there is a mark for \( - 1 \) and \( 0 \)? Wait, maybe I misread. Wait, the number line has an arrow up, and the red dot is at \( t \), with \( - 1 \) below (closer to 0?) Wait, no, the labels: "The number line shows an unknown number, \( t \)". The red dot is at \( t \), and below, there is a mark for \( - 1 \) and \( 0 \)? Wait, maybe the number line: let's see, the positions: 0 is at the bottom? No, the arrow is up and down. Wait, the key is: if \( t \) is equal to \( - 1 \)? Wait, no, the red dot is at \( t \), and the label "1" is in red? Wait, maybe the number line: the red dot is at \( t=-1 \)? Wait, no, the text: "Is \( t - 1 \) positive or negative?". Let's assume from the number line, \( t \) is at \( - 1 \)? Wait, no, maybe the number line has \( t \) at a position less than 1? Wait, no, the number line: the red dot is at \( t \), and below, there is \( - 1 \) and \( 0 \). Wait, maybe \( t=-1 \)? Wait, no, let's think again. If \( t \) is, say, from the number line, the red dot is at \( t = - 1 \)? Wait, no, the labels: "1" is in red, and \( - 1 \) is in blue? Wait, maybe the number line: the red dot is at \( t=-1 \). Then \( t - 1=-1 - 1=-2 \), which is negative. Wait, but maybe the number line: the red dot is at \( t \) which is less than 1. Wait, the problem is: the number line shows \( t \), and we need to find if \( t - 1 \) is positive or negative. Let's recall: if \( t<1 \), then \( t - 1<0 \) (negative). If \( t>1 \), then \( t - 1>0 \) (positive). From the number line, the red dot (t) is at a position to the left of 1? Wait, the number line: the arrow is up (positive direction), and the red dot is at \( t \), with \( - 1 \) below (closer to 0) and 0 at the bottom? Wait, maybe the number line is drawn with 0 at the bottom, and the red dot is at \( t=-1 \). Then \( t - 1=-1 - 1=-2 \), which is negative. Alternatively, maybe the number line has \( t \) at a position where \( t<1 \), so \( t - 1<0 \), so \( t - 1 \) is negative.

Step2: Determine the sign of \( t - 1 \)

If \( t \) is less than 1 (from the number line, as the red dot is at a position left of 1, or at \( - 1 \)), then subtracting 1 from \( t \) (which is already less than 1) will make it more negative. So \( t - 1 \) is negative.

Answer:

negative
