Objective 
The student will write an equation of a line in slopeintercept form given the slope and one or two points. The student will also be able to write an equation of a line that is parallel or perpendicular to the graph of a given equation.

Equations of Parallel Lines Practice
In the sketch below, drag around points A, B, and C. Write the equation of the line through C that is parallel to the line through A and B.

SOL 
AII.6 
The student will recognize the general shape of function (absolute value, square root, cube root, rational, polynomial, exponential, and logarithmic) families and will convert between graphic and symbolic forms of functions. A transformational approach to graphing will be employed. Graphing calculators will be used as a tool to investigate the shapes and behaviors of these functions.
