Parallel and Perpendicular LinesFinding the Negative Reciprocal:
Examples:
1) Find the negative reciprocal of 2.
2) Find the negative reciprocal of78
Unit 3 Day 2 Notes
Example:3). For the line that runs through the two points (6, 3) and (4, 6) find the slope of a line parallel and the slope of a line perpendicular to the given line.
Finding Parallel & Perpendicular Slope:
Determining if Two Lines are Parallel & Perpendicular:
Example:4). Determine if the following two lines are parallel, perpendicular or neither.
3y - x = 12 and y = -3x + 1
Writing Parallel and Perpendicular Lines:
5). Write the equation of the line that passes through point (2, 4) and is parallel to the line
.2 2y x �
Examples:
6). Write the equation of the line that passes through point (6, 5) and is perpendicular to the line -6x - 2y = 12.
