Think about what you know about single linear equations and inequalities, along with what you've
learned about systems of linear equations and inequalities. list some similarities and differences
between two-variable systems of linear equations and of linear inequalities. although you haven't
solved either type of system yet, what similarities and differences do you think there might be in the
solutions to these systems?
[hint: recall that the solution of a one-variable linear equation (for example, 5 = x) is a single point on
a number line. the solution of a one-variable linear equality (example, x < 5) is a segment or region
on a number line. to display solutions to two variable linear equations and inequalities, we use a
two-dimensional graph with x and y coordinates.
