First, we will review
HW: pg 357-8, #s 1*, 2*, 6 & 9 (* indicate written response questions)
Then, we will review the connect between representing equations (functions) as both lines on a cartesian plane as well as lists of coordinates.
HW: pg 325-6, #s 14, 20, 30*, 38 (* indicate written response questions)
The last video uses perpendicular lines to begin explaining how the point where two lines (equations) cross is a common answer (solution) for the two lines. This is the definition of a solution of a system of linear equations.
