Two variables are in direct proportion if each variable changes at the same rate. In other words, if x{\displaystyle x} changes by a certain factor or constant (k{\displaystyle k}), then y{\displaystyle y} changes by that same constant (k{\displaystyle k}). The equation will have two variables and a constant. If you are not given the equation, you cannot use this method. For example, you might be given the equation yx=32{\displaystyle {\frac {y}{x}}={\frac {3}{2}}}. The equation is y=kx{\displaystyle y=kx}, where y{\displaystyle y} equals the y-coordinate of a point on the line, x{\displaystyle x} equals the x-coordinate for that same point, and k{\displaystyle k} is the constant, or slope of the line. Use algebra to rearrange the equation in the form of y=kx{\displaystyle y=kx}. If you can’t rewrite the equation in this form, the variables are not directly proportional. If you can, it proves that they are directly proportional. For example, if you multiply both sides of the equation yx=32{\displaystyle {\frac {y}{x}}={\frac {3}{2}}} by x{\displaystyle x}, the equation becomes y=32x{\displaystyle y={\frac {3}{2}}x}, which is in the form of y=kx{\displaystyle y=kx}, with 32{\displaystyle {\frac {3}{2}}} being the constant.

Article: Negotiating your school career is a common problem for antisocial people. It's important to remember that you're not above your peers, your teachers, or anyone at your school. The more you can accept the things that make you alike, instead of focusing on the ways in which you're different, the easier getting through school will be.  If you struggle to make friends in school, things can be a lot more challenging. Try to find a small group of people that you trust and enjoy to spend time with. Often, people who struggle with antisocial tendencies can thrive with a good group of friends. The "popular" kids at your school don't make for ideal friends in every case. Ignore them and make a different group of friends. Antisocial teenagers commonly describe a disdain for the popular crowd, and it's always more healthy to ignore that scene as much as possible. The workplace can be another challenging environment for antisocial people. Having to deal with a variety of personalities and authority figures can tax anyone's social skills, especially if you prefer your own company. While lots of the specifics of negotiating your work day will have to do with your particular job, you can learn to do a few things to keep yourself happy and healthy.  Avoid group projects and collaborative efforts, which can cause conflicts for people with antisocial tendencies. Do your own work. Nod and smile to authority figures. You don't have to like your boss, but if you want to keep your job, you need to keep your feelings under control. Avoid awkward confrontations. Have a variety of other hobbies and interests outside of work. If work proves to be a challenging social environment, make friends and spend time doing lots of things outside of work to help keep your personal time busy and engaged. Big crowds of people yelling and dancing and screaming and taking selfies? Parties are a big bummer for introverts and antisocial people alike, and trying to negotiate invitations can cause stress and anxiety. Stop worrying about whether or not you'll let an acquaintance down by not showing up to the party because you want to stay home and read. Plan to make a quick stop in and then go back to doing what you want to do.  Do a quick run through the party, stay long enough for a snack and a free drink, make a break for the bathroom, then ditch out the backdoor and make your getaway. If you can't sneak away, make up an excuse to leave, or don't. You don't owe anyone an explanation more complicated than, "Well, I've got to get going. Good party!" If you pick up your kids from school and want to avoid awkward, pointless conversations with the other parents while you wait, just learn to time your trip better to avoid having to wait for long periods of time. Grab a coffee on your way to the school and show up the moment school lets out. Wait in your car until you see your child, then make up an excuse to get going. Fake a phone conversation, if you need to. You don't need to be a great actor to pick up your phone and say, "Mmhmm...yeah" once every 20 seconds or so. Antisocial behavior is generally characterized as a disorder, not something that someone chooses, because it involves an inability to follow the traditional laws and expectations that govern a society. People displaying antisocial behavior may have repeated problems with arrest or other behavioral problems. Other signs of antisocial behavior in need of medical and psychological evaluation include:  Repeatedly lying or conning others Failing to plan for the future Overly aggressive behavior and recklessness Inability to keep a job Lack of remorse for behaviors
