can someone explain to me slope. as related to math? y=mx+b. parents helping with homework.?

Here is a good page describing slope.\n\nhttp://mathforum.org/cgraph/cslope/slope.html

slope=1\ny=x+b\n-3=3+b\nb=-6\ny=x-6

Slope is defined as increase in y over increase in x,\n\nIncrease in y is 5-2=3\nIncrease in x is -3/4-5/4=-0.5\nSo slope is 3/(-0.5)=-3/2

to find an equation.......\n\ny=mx+b\n\nm=slope \nb=y-intercept

The slope is 1.\n\nThink about it this way.  All lines have the same formula:\n\ny = mx + b\n\nm = slope\nb = y intercept\n\nSince there is nothing in front of the x, the slope is 1 because \n1*x = x

Slope is Y2 -Y1 divided by X2 - X1\n\nIn your example, Y2= 12\n                            Y2= -7\n                             X2= 0\n                            X1=-2\nSo... \n(12-(-7)) / (0-(-2))= 19 / 2 = 9.5\n\nThe slope of the line is 9.5

Convert the equation given in the form of y=mx+c and  "m" indicates the slope .In this particular problem the given equation is y+x=4 (or is it y+x-4=0 ?),therefore re-write it as y=- x+4.The co-efficient of x is 1.Therefore,the slope is 1,\nAs for drawing the graph ,in the equation y=-x+4 ,you take different values of x and calculte the corresponding values of y.Let us take the values of x as 1,2 and 3 respectively.The corresponding values of y would be 3,2 and 1.So plot three points on your graph paper with co-ordinates of (1,3),(2,2)and (3,1).[each point indicating the value of x and corresponding value of y found from our precvious calculation].Now,draw a straight line joing these three points and extend them on either sides.This is the graph of the equation

okay your slope is 6\nso plug int he x's and why's\ny = mx +b\n2 = 6(-7) + b\n2 = -42 + b\n44 = b\ny = 6x + 44

Yes because to find slope you need change in y and change in x (or whatever coordinate system you use).\n\nSince you have both two x's and two y's then you're set.\n\nUse this formula: Δy/Δx where Δ stands for "change in" or (y1 - y2)/(x1 - x2)\n\nUsing the coordinates listed:\n(-2 - -2)/(6 - -8)=\n(-2 + 2)/(6 + 8)=\n(0)/(14)\n\nSince '0' divided by anything is zero, your slope is zero.\n\nThis would be a line that is parallel to the x axis 2 units below the axis.

50 because if you rearrange it in the format of y=mx+b with m being the slope it would equal to 50 in your case

y = mx is the general equation for a straight line on cartesian coordinates. So F = ma is also similar with m as the slope, a as the independent variable and F as the dependent variable even though physically this makes no sense. So just plot it on the coordinate system now...\n\nAyerhs.

3/4 is the slope if u put it in the format of y = mx + b\n\nor \n\ny = .75x + 1

a/x + b/y = 2\nlet 1/x = X and 1/y = Y\nSo aX + bY = 2\nSo slope = -a/b = 3/4 (= 0.75)\n  Y intercept = 2/b = -0.5\nThus b/2 = -2\nb = -4\nSo a = 3

ok so the standard equation of a line is y = mx + b, so you want to get the second equation into that form:\n\n5y = 12- 3x\ny= 12/5-3/5X\nso the slope here is -3/5\n\nfor the set of two points:\nthe equation for a slope is (y2-y1)/(x2-x1) so:\n(7-3)/(4-2) = 4/2\n\nso 2 is greater than -3/5 therefore, the slope of the first line is larger

The  y coordinate is the same in both sets of coordinates the equation for this line is line y=-2. \n\nThis line is perfectly horizontal => the slope is 0.

Remember the slope-intercept form?\n\ny = mx + b.\n\ny = the y coordinate.\nx = the x coordinate.\nm = the slope.\nb = the y - intercept.\n\nyour equation is already in slope-intercept form. so all you need to do is match up your numbers with the y = mx + b.\n\nThe slope is -5.\nThe y - intercept is -17.\n\nHope that helps :)

y = mx + b\n\nm is the slope (rise over run).  You have two coordinates (x1,y1) and (x2,y2).  Rise is y2-y1, Run is x2-x1.  So in your example, Rise = 6, Run = -5.  Slope = Rise/Run or -6/5\n\ny = -6/5x + b\n\nb is the y-intercept.\n\nPlugging in one of your coordinate x=3, y=-5\n-5 = -(6/5)(3) + b\nSolve for b and you have\nb = -5 + 18/5\nb = -25/5 + 18/5\nb = -7/5\n\ny = -6/5x -7/5\n\nTo double check, let's put in the second coordinate of x = -2, y = 1\n\n1 = -6/5(-2) -7/5\n1 = 12/5 - 7/5\n1 = 5/5\n1 = 1\n\nThis is consistent, so there is your answer:\n\ny = -6/5x -7/5
