What does the "M" & "B" stand for in Y=MX+B?

i know what they represent, but what do the letters actually stand for?

    Those letter are simply arbitrary, they don't actually stand for anything. You could replace with any other letters (other than x or y, of course) and the equation would be exactly the same. In fact, some teachers, instructors, professors do use other letters than m and b.

    The letters M and B are representative of values and could be just about anything. They are a algebriac expression which represents angles. In your formula the X plane is horizontal and the Y plane is vertical. Because you are using the ordered pairs X and Y I assume that you are working with planes. Consider Y=2X+5 The bar on the plane changes the M/B value as it is moved. X and Y are constants and M and B are variables.

    M stand for the slope of the line i.e the angle it makes with the X axis measured in anticlockwise direction

    B stands for the the length of the imtercept it cuts with the Y-axis

    In math, the variable M stands for slope (y2-y1 divided by x2-x1) and the b stands for the y-intercept, which is the coordinate at which the graph of a line intersects the y-axis. (y-axis goes up and down)

    The letters don't stand for anything.

    They're just variables.

    If that's what you're asking.

    M means the slope and b is y intercept( where the point hits the line on the y axis!)

    Good luck!

    Amazing how many people don't respond to what you ask - but that doesn't stop them from responding just the same.

    I don't know why we use M and B instead of any other letters.

    m is slope

    b is yintercept

    i guess i didnt read your question either...sorry yeah i dont think they actually stand for anything . i hate math!!
