Algebra (Class 60)
Overview
Today we practice using polynomial long division and we return to take another look at equations of lines-- in particular we find how to determine the slope when given the coordinates of two points.
Textbook Sections
§6-7 (Txt. p274) Polynomial Long Division
§8-3(Txt. p.360) Slope of a Line
Key Attitudes
Mathematics is about generalizing and applying patterns.
Key Ideas
Polynomial division works like long division with numbers
Place holders need to be used when the dividend is missing terms.
The slope of a line can be found by calculating the ∆y/∆x
The slope of a line can be used to find other points on a line.
