because writing out all the solutions is not necessarliy a correct answer but a number line is and because graphing out also helps you get a mental image of the concept.
This is called an inequality.
An inequality is similar to an equation, in that it compares two expressions. But in an equality, instead of an equal sign, you would usually use one out of the following inequality symbols:* less than * less than or equal * greater than * greater than or equal
An inequality is similar to an equation, except that instead of an equal sign, it uses one of the following signs: * less-than * less-than-or-equal * greater-than * greater-than-or-equal
If the graph is a two-dimensional plane and you are graphing an inequality, the "greater than or equal to" part will be shown by two things: (1) a solid, not a dotted, line--this part signifies the "or equal to" option--and (2) which region you shade. Shade the region that contains the points that make the inequality true. By shading that region, you are demonstrating the "greater than" part.
In an inequality, you have to shade a side of a line to see show if the possible answers are greater than or equal to it
In an equation, what is to the left of the equals sign equals what is to the right. In an inequality, the left side is either less than, greater than, less than or equal to, or greater than or equal to the right side.
A dashed line is used when the equality is equal to and less than/more than. (≤, ≥) A solid line is used when the inequality is just less than/more than. (<, >)
A number is an expression. It is not an equation, or an inequality, since it doesn't have an equal sign, or an inequality (greater than, less than, etc.) sign.

Shade upward if the inequality involves a "greater than" comparison. Shade downward if the inequality involves a "less than" comparison.
If the inequality is > or< then it is an open circle. If it is greater than or equal to or less than or equal to, it is a closed circle.
In that it uses an inequality sign (less then, greater than, less-than-or-equal, greater-than-or-equal) instead of an equality sign. When solving, special care must be taken - when multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality sign changes.
The word "is" implies equality - an equation. An equality would be expressed different, for example, "is more than", "is at least", etc.
3x = 114 is an equation because it states that two expressions are equal to each other, whereas an inequality would involve a greater than, less than, greater than or equal to, or less than or equal to sign.
It means that the inequality is less than the value of the dashed line and is not equal to it.
It is considered an inequality.
