This is a Unit package for an Algebra 1 or Geometry course. These are worksheets/handouts that can be used as notes or as practice/homework sheets. Included is an introduction to the coordinate plane and the slope between two points. The equation of a line is introduced and students determine whether or not points lie on a given line. Students practice solving linear equations for y to begin graphing. Students then graph linear functions. Lessons on writing the equations of lines are included, as well as a brief introduction to parallel and perpendicular lines. The unit concludes with students graphing linear inequalities.
