Picture this... You are sitting in class and your teacher asks you to make an equation of two coordinates. Oh! You have no idea how! Oh well, just throw that thought away! No, don't, just kidding. You need to make that equation so you can have that happy little A+! To get that A+ however, there are some steps! Here's how...
Delta Y over Delta X. What the heck is it! Well what's "y"? It's the vertical line that is on you graph. So that means "x" is the horizontal line on your graph. So let's say that the teacher's coordinates he gives you are (4, 6) and (3, 5). Just do delta y over delta x. So even though you have x and y in one coordinate (4, 6) is going to stand for Delta y. In "Delta Y over Delta X" over = subtract. So (3, 5) is going to be your Delta X and will be subtracted from you Delta Y.
Your answer should be (1, 1) because once you've subtracted the coordinates from one another that should be your answer. So do you know what (1 ,1) is? Well, in the equation, y = mx + b, (1,1) is m. Plug in the number an figure out b. Y = 5, X = 3, and M = 1 (because 1 divided by 1 is 1.)

Sometimes things seem really tricky because the directions have too many words or numbers in them. A lot of the time, the questions might be tricky, but a lot of the time, they're not! Sometimes you just have to read the questions over and over again until you finally get it. And if you can't get it, then ask a teacher, friend(s), or even your parents. They all know what to do and so do you. Oh! You might want to know what happened to you in the story! Well, here it is...
Your teacher is disappointed because a lot of the student's paper's he's graded have been incorrect. He comes up to you and takes your paper. A small smile lights up across his face as you wait impatiently. He writes something on your paper then drops in it the center of your desk and walks to the next student. What did you do wrong? You hold your paper in the air and look at what he wrote. In red ink there sits a small, simple, but the best A+ ever!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Then you ride away on a purple unicorn!
Here's the technical equation for your "mathmatical" life,
