**9.0a:**Students solve a system of two linear equations in two variables algebraically and are able to interpret the answer graphically. ~~Students are able to solve a system of two linear inequalities in two variables and to sketch the solution sets~~.

**8.0:**Students understand the concepts of parallel lines and perpendicular lines and how those slopes are related. Students are able to find the equation of a line perpendicular to a given line that passes through a given point.

## Today's Objective

Students will be able to use a graph to find a solution that will work in each of two linear equations.
