Question

Which graph shows the inequality ?

The number line goes from negative 8 to positive 8. At 0, there is an open circle. The number line is shaded to the left of 0 and on the left end of the shaded line there is a left-facing arrow.


The number line goes from negative 8 to positive 8. At 0, there is a filled-in circle. The number line is shaded to the left of 0 and on the left end of the shaded line there is a left-facing arrow.

Answer 1

A) The number line goes from negative 8 to positive 8. At 0, there is an open circle. The number line is shaded to the left of 0 and on the left end of the shaded line there is a left-facing arrow.

Explanation:

Given inequality: x < 0

open circle: < or >

filled circle: ≤ or ≥

Therefore, for x < 0 there will be an open circle at 0.

< means less than, so the number line will be shaded to the left of 0 and there will be a left-facing arrow on the end of the shaded line.
