Question

Which inequality shows that -15 is to the left of -10 on a horizontal number line? (A) -15 > -10 B -10 > -15 © -10% > -15 D |-15

Answer 1

(B) -10 > -15

Explanation:

You want the inequality that shows -15 is left of -10 on a number line.

Ordering

A horizontal number line has more negative numbers on the left and more positive numbers on the right. More negative numbers are less than more positive numbers. Conversely, more positive numbers are greater than more negative numbers:

-10 > -15

Additional comment

The "less than" symbol (<) has the puts its operands in the same left/right order they have on the number line. Sometimes we like to use this symbol for answers to inequalities because of this visual effect.

-15 < -10
