what is the slope of y=-5x+4?
350432
-5/1 meaning you go down 5 units and over 1

x=5x-y\n\nx-5x=-y\n\n-4x=-y\n\ndivide both sides by -4\n\n(-4/-4)x=(-y/-4)\n\n1x=(1/4)y\n\nx=y/4

I'll help :)\n\nSlope is calulated by taking the change in y over the change in x.  So (78-92)/(5-9)=  -14/-4 = 7/2\n\nThe slope is 7/2

Point slope form:\n\ny-(-3)=(1/2)(x-5)

4x - 5y = 2\n5y = 4x - 2\ny = 4x/5 - 2/5\n\nThe slope of this is 4/5, so the slope of the perpendicular is -5/4 (just take the opposite of the reciprocal).\n\nFor the new line, m = -5/4, and you have a point (2, -1).  Using the point-slope formula,\n\ny - y1 = m(x - x1)\ny - (-1) = (-5/4)(x - 2)\ny + 1 = -5x/4 + 5/2\n5x/4 + y = 3/2\n5x + 4y = 6

slope equals rise/run. slope=4 y-intercept=-20

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.

y=mx+b\n\njust rearrange it so you get b as your intercept..\n\nin this case y=-1/4x +3, so the slope is -1/4, and the intercept is 3

slope m = (2-5)/(5--2) = -3/7\n5=-3/7*2+b\n5+6/7 = b = 35/7+6/7=41/7\n\ny =-3/7x+41/7

x-4y=-20\n=> -4y=-x-20\n=> 4y=x+20\n=> y=x/4+5 Ans.\nThanks.

x/ -4 + 5 = 1\nsubtract 5 from both sides\nx/ -4 = -4\nthen multiply both sides by -4\nx = 16

y= -3x +5\n y= -4x -1  subtract\n0=x+6    subtract 6\nx=-6\nsubstitute\ny=-3(-6)+5\ny=18+5=23\nsolution is (-6,23)\n\ncheck \n23=-4(-6)-1\n23=24-1

the slope is 4\nwhen an equation is in standard form:\ny=mx+b\nm (which is the coefficient of x) is the slope

Slope is the "change in y" divided by the "change in x" (AKA "rise" over "run").\n\n(x1, y1) = (-2, 4)\n(x2, y2) = (2, -1)\n\nThus:\n\nm (slope) = "delta y"/"delta x" = rise/run\nm = (y2 - y1)/(x2 - x1)\nm = (-1 - 4)/(2 - (-2))\nm = -5/4\n\nrun = 4, rise = -5

y-int= (0,-5)\nx-int= (-1.2,0)

1. Since 5y = 15x + 35, y = 3x + 7, and the slope is 3.\n\n2. Since 3x + y = 7, y = -3x + 7, and the slope is -3.

X+Y=5\n\nHence Y=(5-X)\n\nHence Y/4 = 5/4 - X/4\n\nHence your first equation is\n\n(X^2)/6-(5/4-X/4)=1\n\nX^2+3X/2-27/2=0\n\n2x^2+3x-27=0\n\nx= (-3 +/- 15)/4\n\nx= 3 or x= -9/2\ny= 2 or y= 19/2\n\nSo either x=3, y=2 or x= -9/2, y= 19/2.\n\nP.S. I assumed that x^2/6 means (x^2)/6 and not x^(2/6) which would be much more difficult.\n\nGood luck.
