When graphing equations, why is there is always a dot? Either a decimal, a circle to represent something, or a mulitplication sign. Luckily, I've got your back so there is no need to worry. When graphing inequalities or equations, there is always a graph with a dot to represent a number. Sometimes the dot is filled in, that means that what you are trying to solve for, could be equal to that number. If the problem states that the number is between 35 and 40 that means could fill in that bubble. You would do that because it is between but ALSO including. The number could be 35 or 40!!! Sometimes you need to look into the sentence. That means to take a closer look at the problem and look at what is wants you to do.
See, equations and inequaltities are a lot easier than you think. Just read your problem over and think about what it is asking you to do. Is it including or no? Does it want you to graph it or not? See! Ask yourself those questions! You'll see what a difference it makes!
