I am working on graphing inequalities on an anchor chart. Does anyone know what ≠ means when graphing inequalities? If so, could you also link an example please. (just search "graphing inequalities anchor chart" to get an image of what I'm working on)
≠ means "not equal to" in other words, an inequality.
≠ means "not equal to"
can you link a example or something please?
4 ≠ 3
There is nothing complicated about it. It means just what it says.
the equation is x ≠-4
is it an open circle or closed? How am I supposed to know without the underline?
im supposed to answer what the model would be to it
Oh, you are on a number line.
-4 has an open circle around it because it is not included. There are solid lines left and right of -4
If it were x = -4 it would be a black dot at -4
if it were x> -4 it would be circle and line to right
if it were x >/= -4 it would be black dot and line to right
The symbol "≠" in mathematics represents "not equal to." When graphing inequalities, "≠" is used to indicate values that are not equal. In other words, it signifies that the values on either side of the symbol are not the same.
To graph an inequality, you can follow these general steps:
1. Identify the type of inequality (e.g., greater than, less than, greater than or equal to, less than or equal to, not equal to).
2. Rewrite the inequality in slope-intercept form, if necessary, with "y" on one side and everything else on the other side of the equation.
3. Determine whether the inequality is a solid or dashed line based on whether the symbol includes or excludes the equal sign ("≤" or "<=" represents a solid line, while "<" or ">" represents a dashed line).
4. Plot the line on the coordinate plane using the y-intercept and slope, if present.
5. Shade the appropriate region based on the inequality:
- If the inequality is "≤" or ">=", shade the region that includes the line.
- If the inequality is "<" or ">", shade the region that does not include the line.
- If the inequality is "≠," shade the entire plane except for the line itself.
To find an example of graphing inequalities on an anchor chart, you can search for "graphing inequalities anchor chart" on an internet search engine. This search should provide visual examples that can help guide you in creating your own anchor chart.
