Two lines are parallel if they have the same slope. To determine if two lines are parallel, write their equations in slope-intercept form and compare the slopes. Two lines are perpendicular if the product of their slopes is -1. To find a line perpendicular to another line, take the additive inverse of the other line's slope. The chapter discusses parallel and perpendicular lines and includes class examples and homework problems determining if lines are parallel or perpendicular.

This document discusses families of linear graphs and their characteristics. There are two basic families: graphs that have the same slope, and graphs that have the same x or y-intercept. Graphs belong to the same family if they have a common slope or intercept when their equations are plotted or written in point-slope form. The simplest graph in a family is called the parent graph, such as y=x being the parent of graphs like y=3x and y=1/4x that have the same slope. The document provides examples and problems for students to work through related to identifying families of graphs and analyzing parent graphs.

Two lines are parallel if they have the same slope. Parallel lines will never intersect and their slopes are equal. Two lines are perpendicular if their slopes are negative reciprocals of each other, meaning their product is -1. To find the equation of a line parallel or perpendicular to a given line through a specific point, you take the slope of the given line and use that or its negative reciprocal in the point-slope formula.
FORM 5: Linear Law
When two variables are related linearly, plotting their values results in a straight line. This straight line of best fit can be used to add or subtract linear relationships, whether the lines are parallel or non-parallel. Vectors can be added by treating the linear lines of best fit for each variable as vectors, with the resultant vector representing their sum.

Planes, Lines and Transversals
Parallel lines are coplanar lines that do not intersect. Skew lines are non-coplanar lines that are neither parallel nor intersecting. A transversal is a line that intersects two or more coplanar lines at different points, forming interior and exterior angles. Interior angles are in the region bounded by the lines, while exterior angles have only one line as their boundary. Corresponding angles, alternate interior angles, alternate exterior angles, vertical angles, and linear pairs are special angle relationships formed by transversals.

The document discusses two methods for graphing linear equations:
1) Find the x and y-intercepts by setting either x or y to 0 and solving, then plot those two points and draw a line through them.
2) Rewrite the equation in slope-intercept form y=mx+b, plot the y-intercept at (0,b), use the slope m to plot two more points, and draw a line through all three points.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
