ezplain how you would determine the slope of the equation 2x-8y=7?

Solve for y\nSubtract 2x from each side\n-8y = -2x + 7\nDivide everything by -8\n-8y/(-8) = -2x/(-8) + 7/(-8)\ny = (1/4)x - 7/8\nFor the equation y = mx + b, the slope is m.\nAnswer: slope = 1/4

(6y^2-3y)(y+7)-->(2y)(y-1)(y+7)\nif that helps

when you multiply the 2 through on the right side of the equation you get:\ny = 2x-2+3\ny = 2x+1\nthe slope of this line is the number in front of the x.

y = mx + b\n\n"m" is the slope, which is the rise over the run.  y2-y1 / x2/1 = (1-3)/(3-2) = -2/1\nSo, m = -2\n\nPlug in a set of coordinates to find b...\n3 = -2(2) + b\nb = 7\n\nSo, the equation is y = -2x + 7\n\nIn yout case, you want it as Ax+By+C = 0\nThis would be 2x + y - 7 = 0

slope is a fraction found by subtracting the two y-coordinates and putting this on top, then subtracting the two x-coordinates (in the same order as you did for y) and putting this on bottom.  So, either\n\n(4-2)/(1- -6) = 2/7\n\nor\n\n(2-4)/(-6 - 1) = -2/-7 which is also 2/7 since a negative divided by a negative is positive

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.

2x + y = 7\ny = -2x + 7\n\nThe slope of this is -2, so the slope of the perpendicular is 1/2.  Using the point-slope formula, you can find the equation of the other line:\n\ny - y1 = m(x - x1)\ny - 4 = (1/2)(x - 4)\ny - 4 = x/2 - 2\ny = x/2 + 2

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

Subtract 2x from each side\n-y = 0 - 2x\nMultiply each side by -1\ny = 2x

you solved it right, since the line BC never goes up/down(the y-coordinate never changed, graph it and you'll see) the slope is 0. and 0/7=0, so you're right.\nit would be impossible if you got 7/0, because you can't divide by 0.

It's already in slope and y-intercept form...  y = mx + b, so slope (m) = 7, y-int (b) = 0

equation of slope is (y2-y1)/(x2-x1)\n\n(8,-2) means x1=8 and y1=-2\n(3,5) means x2=3 and y2=5\n\nso slope= (5-(-2))/(3-8)\n=7/-5\n\nso slope= -7/5

First, you'll move the 6x to the other side to create the equation y=mx+b.  M=Slope.  Divide by 5 to get Y by itself, then you're left with y=-6/5x+13.  So slope is...\n\n-6/5

No - the slope is going to be a number, not an equation.\n\nd/dx (2x^2) = 4x\n\nAt x = -2, the slope will be -8.\n\nThe equation of the tangent LINE would be\n\ny + 8 = -8(x + 2)\n\ny = -8x - 24, as you have it.\n\nAnd no - getting the terminology right is not a minor point.
