Learning goals: Teacher Facing Interpret inequalities that represent situations with a constraint. Solve an equation of the form $px+q=r$ to determine the boundary point for an inequality of the form $px+q \gt r$ or $px+q \lt r$. Use substitution or reasoning about the context to justify (orally and in writing) whether the values that make an inequality true are greater than or less than the boundary point.
