A.7d - The student will investigate and analyze function (linear and quadratic) families and their characteristics both algebraically and graphically, including x- and y-intercepts.

## Standard Form

You are able to manipulate the line by using the sliders to move points R and S.
Notice the general form of standard form and the equation of the line in standard form. Note the variables (A,B,C) and their corresponding values.
