Concepts for March 30th

Algebra I

Today we discussed
Our discussion about functions and graphing is almost complete.  Today we introduced the concepts of parallel and perpendicular lines. Students should be able to take a set of ordered pairs and determine if they are a function, what the slope of the line is that contains the two points, and how to put the equation into point-slope form, slope-intercept form, standard form, function notation, and determine the x- and y-intercepts as well as find parallel and perpendicular lines.

Sections Covered in Textbook
1)  10-6:  Parallel and Perpendicular Lines (pages 423-426)

Pre-Algebra

Today we discussed
We have finally moved on from solving simple and complex equations to the concept of graphing.  We did a very quick overview of graphing equations and inequalities on the number line, reviewed the coordinate plane, discussed ordered pairs and plotting coordinate points, and finally moved on to finding solutions for equations that have two variables.

Sections Covered in Textbook
1) 8-1: Equations and the Number Line (pages 284-285)
2) 8-2: Inequalities and the Number Line (pages 286-288)
3) 8-3: Ordered Pairs (pages 290-292)
4) 8-4: The Coordinate System (pages 293-295)
5) 8-5: Equations with Two Variables (pages 296-298)
