• Relations, Functions and Linear Equations: Study the definition of relations and functions. Use of mapping, tables, ordered sets and graph to represent relations and functions. Learn how to apply the vertical test to identify a function. Determine the difference between discrete vs. continues functions. Definition of linear equations and the Standard Form.

• Learning About Slope: Slope formula (run vs. rise and two points), falling to the right, horizontal, vertical, negative and positive cases for the slope. Slope of parallel and perpendicular lines.

• Working With Systems of Linear Equations: Slope intercept form and point-slope form problems that involve a point and slope, two points, etc. Solving systems of two variable linear equations by substitution, linear combinations and graphing. Introduction to special functions (step function, constant function, identity function and absolute value function)

• Two Variable Linear Inequalities and Absolute Value Inequalities.  Solving two variable inequalities by shading above o below the graph to indicate the solution set.
