SOL 
A.6  The student will graph linear equations in two variables.
A.7  The student will investigate and analyze function (linear and quadratic) families and their characteristics both algebraically and graphically, including
a) determining whether a relation is a function;
b) domain and range;
e) finding the values of a function for elements in its domain; and
f) making connections between and among multiple representations of functions including concrete, verbal, numeric, graphic, and algebraic.
A.11  The student will collect and analyze data, determine the equation of the curve of best fit in order to make predictions, and solve realworld problems, using mathematical models. Mathematical models will include linear and quadratic functions.
