# Write an inequality for a line graph

Just follow these steps.

With "or" inequalities, we graph the numbers that satisfy either inequality, or both at the same time. In other words, we graph the combination, or union, of both inequalities.

They often include the words "and" or "or. And just to reinforce, you could have done this anywhere.

If we move 2 in the x-direction, if delta x is equal to 2, if our change in x is positive 2, what is our change in y? Compound Inequalities Compound inequalities are two or more inequalities combined in the same statement.

## Write an inequality for a line graph

How to Graph Inequalities We can graph inequalities on a number line to get a better idea of how they're behaving. We can figure out its y-intercept just by looking at it. They often include the words "and" or "or. Compound Inequalities Compound inequalities are two or more inequalities combined in the same statement. If we move 2 in the x-direction, if delta x is equal to 2, if our change in x is positive 2, what is our change in y? But this inequality isn't just y is equal to negative 3. So if you think about this line, if you think about its equation as being of the form y is equal to mx plus b in slope-intercept form, we figured out b is equal to negative 2. So that is negative 2 right there.

So it's all the area y is going to be greater than or equal to this line. Fill in the circle if and only if the variable can also equal that number.

## Writing inequalities from a graph worksheet

Fill in the circle if and only if the variable can also equal that number. Let's say that x is equal to 2. We can figure out its y-intercept just by looking at it. This line will tell us-- well, let's take this point so we get to an integer. Its y-intercept is right there at y is equal to negative 2. Sketch a number line and draw an open circle around that number. So if you think about this line, if you think about its equation as being of the form y is equal to mx plus b in slope-intercept form, we figured out b is equal to negative 2. Now, this inequality includes that line and everything above it for any x value.
