Module 1, Sec. 3.5 Equations of Lines
I.
Review slope-intercept form:
Example 1: Write an equation in slope-intercept form for the line with slope –½ and vertical
intercept of (0, –5)
Two points determine a line. From those two points we can calculate _________________,
then algebraically find the ____________________ ____________________ and then write an
_____________________.
Example 2: Use slope-intercept to find an equation for the line which goes through the points
(–3, 5) and (2, 4). Write your final equation in standard form.
