It is an open dot.
The dot is open, if it is less than or equal to than the dot is closed
a solid dot is , if less tha or equal to, or grearter than or just greater than and less than.
If the inequality includes 'or equal' then use a solid dot [the value is included]. If it doesn't use 'or equal' then use the open dot.
A line which has one end, but stretches off to infinity is called a ray. If we want to show an interval such as [2,infinity) which means all the numbers between two an infinity including two, we put a close dot at two and draw a ray going to the right. Similarly for (negative infinity, 2] we draw the closed dot at 2 but this time the ray goes to the left. Now if we draw an open circle, or a the out line of a dot this mean the interval (2,infinity) where we are considering all the numbers very close to two but not two itself This is an open half line and it represents an open interval.
Multipy by whatever is there in the following example the * is the dot (example 6*9=54

6.5, you have to look at the number right behind the dot. 6.5 is greater than 6.3 because 5 is greater than 3.
A dot is filled in on a number line to indicate that a specific value is included in the set of solutions or the interval being represented. This typically occurs when the number is part of a closed interval, such as when denoting all numbers greater than or equal to a certain value. For example, if representing the range ( x \geq 3 ), the dot at 3 would be filled in to show that 3 is included in the range. In contrast, an open circle would be used for values not included in the interval.
A number line is used to draw the graph of the inequality. The graph of an inequality consists of the graphs of all its solutions.If you graph x < 5 on a number line, the solution is all real numbers to the left of 5. Use an open dot at 5, to indicate that 5 is not a solution.If you graph x > 5, the solution is all real numbers to the right of 5. Use an open dot at 5 to indicate that 5 is not a solution.If you graph x = 5, the solution is all real numbers to the right of 5, included 5. Use a closed dot at 5 to indicate that 5 is a solution.Inequalities that have the same solution set are called equivalent inequalities. Solving an inequality is a process of writing equivalent inequalities until you isolate the variable. To do this, you apply the addition, subtraction, multiplication, division and transitive properties.Examples:x + 9 -6 - 15-3x > -21 divide each side of the inequality by -3, and reverse the order of the inequality (that is, change the symbol of the inequality) ;x -4 and x > 4 the word and signals a conjunction.The solutions are all numbers that are solutions of both inequalities.Use an open dot at -4 and another open dot at 4. All numbers greater than -4 and less than 4 are solutions.x < -3 or x > 5 the word or signals a disjunction.The solutions are all numbers that are solutions of either inequality.Use an open dot at -3 and another open dot at 5. All numbers less than -3 and greater than 5 are solutions.Examples:-7 < 4 - x 1All numbers less than -0.4 and greater than 1 are solutions. Use an open dot at -0.4 and another open dot at 1.
x ≥ - 10.2 On a number line graph all real numbers to the right of -10.2. Use a closed dot to indicate that -10.2 is a solution.
a filled in circle/dot means "greater than or eaqual to/less than or equal to" (depending on which way the arrow is pointing. an empty cirlce means only "greater than/less than". the greater than/less than symbol with the line under it will indicate the filled in circle. the normal greater than/less than symbol willl indicate the hollow cirlce
