- Draw the graph of the corresponding equality. This will divide the Cartesian plane into two parts.
- Evaluate the inequality for the origin, O - the point (0,0). Any point will do, but O it is easy to evaluate it there.
- It the inequality is true, then the part of the plane that contains the origin is the valid region whereas if the inequality is false, the other region is valid.

What is the inequality sign for at least?
The sign is "greater than or equal to" or ≥
What is the equal to or greater then symbol on a graph?
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.
How do you solve an inequality in one variable?
It depends on the specific inequality. In the simplest cases, it is solved just like an equation; except that you must be careful when multiplying and dividing - if you multiply or divide both sides by a negative number, you must switch the inequality sign. For instance, a "less-than" sign would be changed to a "greater-than" sign.
What is inequality in algebric equation?
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
How do you graph the inequality w is greater than or equal to 5?
The answer depends on what space you are working in. In 1-dimensional space, it would be like the number line and the relevant part of the graph would be all point at or to the right of the value 5.

What are the critical features of an inequality?
An inequality must have a greater than sign (>) OR a less than sign (<) OR a greater than or equal to sign (≥) OR a less than or equal to sign (≤).
How can you graph an inequality?
You have to graph an inequality on a number line. For example, x>3.The number 3 on the number line gets an open circle around it, and a line is extended to all the other possible equations.There is an open circle if it is a "greater than or less than" sign, and there is a shaded circle if there is "greater than or equal to, or a less than or equal to" sign.
What is the inequality sign for at least?
The sign is "greater than or equal to" or ≥
Is xl7.6x7.0 an inequality?
No. To be an inequality, it must somewhere have a greater than, less than, greater-or-equal, or less-or-equal sign.
How do I solve this inequality y4x-5?

What side of the graph will the shaded part be if the inequality is greater than?
If it is y is greater than then it is above the line. If it is x is greater than then it is to the right.
What way does an inequality sign face when it is greater than or equal to?
The inequality sign opens towards the bigger number.
Is a number an expression equation or inequality?
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.
What inequality sign means no less than?
Greater than or equal to
What is a sentence called when you have a greater than or less than sign in it?
an inequality
When will the graph of an equation inequality be a dotted line?
The line is dotted when the inequality is a strict inequality, ie it is either "less than" (<) or "greater than" (>). If there is an equality in the inequality, ie "less than or equal to" (≤), "greater than or equal to" (≥) or "equal to" (=) then the line is drawn as a solid line.
