Graph x<=-6

Problem

x≤−6

Solution

1. Identify the boundary point on the number line, which is −6

2. Determine the type of endpoint to use. Since the inequality includes "or equal to" (≤, use a solid (closed) circle at −6 to indicate that −6 is included in the solution set.

3. Determine the direction of the shading. Since the inequality is "less than" (<, shade the number line to the left of −6

4. Represent the solution set in interval notation as (−∞,−6]

Final Answer

x≤−6⇒(−∞,−6]
