If something says "greater than" or "less than" some function, then you will have a dotted or dashed line. The appropriate side of the line is shaded or hashed. If it says "greater than or equal" or "less than or equal", then you use a solid line. Then shade the appropriate side.

MaxineWhen a point arbitrarily close to the boundary point belongs to the solution set but the point itself does not.
Consider the equation 2x - 3 < 0
This is equivalent to x < 1.5
ow any number up to but not including 1.5 belongs to the solution set: for example, 1.4, 1.49, 1.4999999, and so on. But 1.5 does not.

What does it mean when you have an open dot on your graph?
It usually means that the line ends there but does not include that point.
Suppose y is alone on the left side of an inequality After you graph the boundary how can you decide whether to include the boundary in the graph and which region to shade?
If the inequality is strict (< or >) then the boundary is not included. Otherwise (≤ or ≥), it is.
What is the type of circle used on a number line when the boundary point is not part of the solution set?
It is an "open" circle. That is, a circle which is not filled in.
Which type of graph is data plotted by a point on the graph?
