Question
Adjacent figure is a vertical number line, representing an integer. Observe it and locate the points:
If point $D$ is $+ 8$, then which point is $– 8?$
If point $D$ is $+ 8$, then which point is $– 8?$
✓
Answer
Since $D$ is $+8$ then,
$-8$ will be a mirror image of $D$ through $0$ on the number line.
Hence,
According to the given vertical line,
$-8$ will be the point $F$ on the number line.
$-8$ will be a mirror image of $D$ through $0$ on the number line.
Hence,
According to the given vertical line,
$-8$ will be the point $F$ on the number line.
