1) The document provides instructions for homework assignments in math lesson 4-4 that are due on specific dates in December 2012. It includes solving equations written in different forms (point-slope, standard, slope-intercept) and identifying whether lines represented by equations are parallel, perpendicular, or neither. 2) The homework includes practice problems working with parallel and perpendicular lines, writing equations in different forms, and determining if equation pairs represent parallel, perpendicular, or neither relationships between lines. 3) A chapter 4 test is scheduled for December 10th.

Lesson 4.4 WarmUp:
Write an equation in point­slope form for the line that
passes through each point with the given slope.
1) (5, 3), m = 7
Write each equation in standard form.
2) y ­ 10 = 2(x ­ 8)
3) 2y + 3 = ­1/3(x ­ 2)
Write each equation in slope­intercept form.
4) y ­ 11 = 3(x + 4)
5) y + 4 = 3(3x + 3)

Lesson 4.4:
*parallel lines ­ lines in the same plane that never intersect
...and have the same slope
*perpendicular lines ­ lines in the same plane that intersect at right angles
...and have slopes that are "opposite reciprocals"
ie ­­> 3/4 and ­4/3
...and the product of their slopes = ­1
