Which inequality symbol means that -10 is to the left of the other number on a number line?
Understand the Problem
The question is asking which inequality symbol (<, >, or =) correctly represents the relationship where -10 is to the left of another number on a number line. Numbers on the left are smaller than numbers on the right.
Answer
$<$
Answer for screen readers
$-10 < x$
Steps to Solve
-
Understanding the number line
On a number line, numbers increase as you move from left to right. This means numbers on the left are smaller, and numbers on the right are larger.
-
Expressing the relationship as an inequality
Since -10 is to the left of another number, it means -10 is smaller than that number. We can express this relationship using the "less than" symbol, which is <.
-
Writing the inequality
If we represent the other number as $x$, the inequality is $-10 < x$.
$-10 < x$
More Information
Any number to the right of -10 on the number line satisfies this inequality. For example, -9, 0, 1, 100 and so on.
Tips
A common mistake is to confuse the direction of the inequality symbol. Remember that the smaller side of the symbol "points" to the smaller number.
