Finding the Slope of a Line Given Two Points

Today we talked about how to determine the slope of three types of lines: horizontal lines, vertical lines and lines that are neither horizontal or vertical. To be concise, horizontal lines always have a slope of zero. Vertical lines have no slope, which means their slope is undefined. To find the slope of all other types of lines, use the formula found on page of the book. Be sure to substitute carefully, so you don't make any silly errors.

Tonight's Homework: Read Lesson 5.3, and then do 5.3 ( 12 - 35 odd) and page 291 ( 1 - 3 ).
