Question

Which inequality has an arrow pointing to the left when the solution set is graphed on a number line?

Answer 1

Answer:

$x \le 5$

Step-by-step explanation:

Given

Options (a) to (d)

Required

Which represents an arrow pointing left

When an arrow points left on an inequality graph, the inequality is either of the following:

$x < a$ or $x \le a$

From the given options (a) to (d), only $x \le 5$ fits the above description.

Other options illustrate an arrow pointing to the right

To further explain this;

Looking at (b), we have:

$4 \le x$

This is rewritten as:

$x \ge 4$ --- the same form as (c) and (d)
