SOL 
A.4  The student will solve multistep linear and quadratic equations in two variables, including
a) solving literal equations (formulas) for a given variable.
d) solving multistep linear equations algebraically and graphically.
f) solving realworld problems involving equations and systems of equations.
Graphing calculators will be used both as a primary tool in solving problems and to verify algebraic solutions.
A.8  The student, given a situation in a realworld context, will analyze a relation to determine whether a direct or inverse variation exists, and represent a direct variation algebraically and graphically and an inverse variation algebraically.
