The relationship of slope to steepness and methods of calculating slope via rise over run as well as rearrangement into slope-intercept form is covered. Parallel and perpendicular lines are also covered as well as graphing inequalities by graphing their boundary equations and using a test point off the boundary to determine the solution region.

**2021 - Systems of Equations**This segment covers the solution of systems of pairs of linear equations by both the method of elimination (sometimes called the method of addition or the method of row reduction for large systems) and the method of substitution. Graphical representations and notations of dependence and of inconsistency of parallel pairs are also covered.
