Describe the boundary lines for two- variable
inequalities. Why are the boundary lines for two- variable
inequalities with greater than and less represented by dotted
lines? Provide examples.
First, define a boundary line and tell where it comes from. Then,
describe what the boundary line can tell us about solutions to an
inequality. You can also talk about how to know what part of a
graph to shade. Finally , talk about the cases where we use each
type of...
