Writing an inequality from a graph - learn math online

The video tutorial explains how to determine inequalities from a given graph. It starts by identifying the starting point of the graph and analyzing whether the values are less than or greater than a specific point. The tutorial then discusses how to represent these values using symbols and explains the significance of filled and open circle dots. Finally, it concludes with finalizing the inequality using the correct symbols based on the graph's direction.

What is the first step in determining an inequality from a graph?

• Identify the slope of the graph

• Determine the starting point of the graph

• Calculate the area under the graph

• Find the midpoint of the graph

How do you represent a range of numbers that are less than a specific value?

• Using a variable like X

• Listing all numbers individually

• Drawing a line on the graph

• Using a table of values

What does a filled circle on a graph indicate?

• The value is not included

• The value is included

• The graph is increasing

• The graph is decreasing

What symbol is used when the values on a graph are less than or equal to a point?

• Less than or equal to

• Less than

• Equal to

• Greater than

What type of circle is used for inequalities that include the endpoint?

• Dotted circle

• Shaded circle

• Closed circle

• Open circle
