What does y=mx+b stand for, and what does it mean??

Question

what does this mean exactly? all i know is that you use it for slope. a little help here!

Answer 1

oh gosh i knew i should have payed attention last year. IDK lol pay attention in school and dont end up like me!!!

Answer 2

It's for graphing. The M equals the slope and the B equals the Y-Intercept. For example, if you had the equation y=1/2x+3, you would start at 3 on the Y-axis then go up one and over two, and keep repeating that, then voila! You have a line based on that equation. That equation is called slope-intercept form.  

Answer 3

Ok...lets see if I can remember this:

This is the stanard form of an equation.

Y = It is a variable, the dependent variable

M = this is your slope or rate of change, it is a constant.

X = independent variable

b = This is your initial (start with), it is the y-intercept

Answer 4

thats just the equation of a straightline. b being the intercept on the y axis and m being the gradient.

Answer 5

It is the formula for the equation of a late. You can determine the slope through it.

x and y are both variables. Any number values for x and y where the left side of the equation equals the right side of the equation is a point on the line on an xy grid.

m is the slope of the line. Slope is rise over run, or if you were following the line, the number of boxes you have to count upward/downward divided by the number of boxes you have to count leftward/rightward to get to another point on the line.

b is the y-intercept, or the value where the line crosses the y-axis.

Answer 6

IT IS THE FORMULA FOR SLOPE

WHERE M IS THE SLOPE

X AND Y ARE THE POINTS ON THE GRAPH

B IS THE Y-INTERCEPT

YOU CAN USE THIS FORMULA TO FIND THE EQUATION OF ANY LINE IF YOU HAVE THE SLOPE OF THE LINE AND A POINT ON THE LINE OR TWO DIFFERENT POINTS ON THE LINE

Notice that when the slope, m, is positive, the line slants upward to the right. The GREATER m is, the steeper the line will slant upward to the right.

When the slope is negative, the line slants downward to the right, and, as the slope becomes more and more negative, the line will slant downward steeper and steeper to the right.

Also, notice that when the y-intercept, b, is positive, the line crosses the y-axes above y = 0. When b is negative, the line crosses the y-axis somewhere below y = 0. In fact, b is the value on the y-axis where the line passes through this axis. The line intercepts, or crosses, the y-axis here, and, therefore, b is called the y-intercept.

Answer 7

Its the formula for a straight line

mx = the gradient example 5x = 5/1 =5 (its v/h which is vertical / horizontal) so its 5 up and 1 along

and + b (i say + c but its just the same =P) is how many boxes you push it up (-b means down b units)

Answer 8

that's slope-intercept form.

Y and X are the values (x,y)

m is the slope

and b is the y-intercept

graphing this will give you a line.

Answer 9

slope formula and it is completely useless after high school

Answer 10

it is the formula for a slope,

b is where you start on the y axis

mx = the slope of the equation

m is always a number whether its 1 or 10

Answer 11

it is the basic formula of a line

m is slope b is y intercept

Answer 12

it's the formula for slope. I'm not sure what the rest stands for anymore.

Answer 13

y is just the quation. could be a b c f h.

mx is the slope (how many units you go up over how many units you go over)

and b is where the line intersects on the y-axis.

hope this helped. i hated algebra. but I was good at it.

answer mine?
