Perpendicular lines are lines that cross at right angles to eachother. We will use all of our previous line skills and now introduce something called a "negative reciprocal".
Here we will practice how to find a region on a graph that satisfies multiple inequalities. We need to take particular care when deciding whether to use a dotted or a solid line!
The following worksheet will revisit all of the skills you have practiced throughout this block. This is a good chance to see where your graph work is at and to get feedback on what may be worth recapping! Try and answer each question to the best of your ability, and if you need reminding you can watch the videos above. Good luck!
