Algebra I 806 is presented in two student-book parts: 806A and 806B. Students develop their skills in writing and graphing linear equations using slope-intercept form, point-slope form, the slope formula, and two given points.

They study horizontal and vertical lines and learn to write equations for parallel and perpendicular lines. The unit then introduces relations and functions, domain and range, and function notation. Chapter reviews, a unit review, and the unit test included in 806B bring together the work from both parts.
