Graphing Lines

We reviewed the 3 different types of lines that can be drawn on a coordinate grid: vertical, horizontal and sloped (diagonal, as defined by Chris). Vertical lines can be described by an equation of the form x = k, where k is a numerical constant. Horizontal lines can be defined by an equation in the form of y = k. Sloped lines can be described by equations of the form Ax + By = C, where A, B, and C are numbers.

Tonight's Homework: Read Lesson 4.2, and then do 4.2 ( 12 - 20, 21 - 48 FCO and 67 - 70 ).

P.S. Get well, Grace and Kelsi!!!
