What would be an equation in slope-intercept form for x-4y = - 20 ?

The only way to do it is that you use the slope intercept formula which is y=mx+b so then you change the equation to be in that order. you bring the x to the other side of the equation and now it should look like this -4y=-x-20. So then you bring the -4 and subtract it from -20 you get -16. Finally the equation should look like this y=-x-16. and thats your final answer.Try to remember the slope intercept formula its gonna be very important in Geometry class.

slope:-8. y-intercept:-7. Whatever number is in front of the x is always the slope. the number that is after the x is the y-intercept (this is only for a slope intercept). Good luck and choose me as the best answer please :)

there are a couple of ways to do this, but I think the easiest is to find the slope and since you know the y-intercept, use that formula.\n\nm= (-4-0)/(0-12)\n\nm=-4/-12\nm=1/3\n\ny=(1/3)x -4

First you need to solve for y... y = 4/3x-4\nThen by using the Y = MX+B formula you will see M = 4/3 which is your slope. B = -4 which is your Y-Intercept. Plot your Y-Intercept at (0,-4) and then plot the next according to your slope, which is Rise/Run. so from (0,-4) you will go up 4 and over 3. you should end up at (3,0). after that all you have to do is connect the dots....

you would take the 2x-4y=3 and solve for a variable, such as x=(3-4y)/3   you now have what x equals and you sub that into the other equation so you now have 2[(3-4y)/3]-3y=0 and you should be able to solve that equation

for (0,2),(4,0) the slope is -1/2\nfor (-2,0),(4,0) the slope is 0

First equation:\n4x + 2y = 10\n\nRearrange to get the y-term alone:\n2y = 10 - 4x\n\nDivide both sides by 2 to get it in slope-intercept form (y = mx + b):\ny = -2x + 5\n\nNow you can graph it by drawing a line through (0,5) as the y-intercept and have it go down at a slope of -2 through points (1,3), (2,1), (3,-1), etc.\n\nFor the second equation, draw a horizontal line for y = 4\n\nYou'll see they intersect at the point (½, 4).  I've attached a graph of the two lines...\n\nSo your solution is:\nx = 0.5 (or ½)\ny = 4

4x+2y=8\n\nSubtract the 4x to the other side to get\n\n2y= -4x + 8\n\nDivide the 2 on all sides to get:\n\n2y(/2)= -4x(/2) + 8 ( /2)\n\nYour final answer will be:\n\ny= -2x + 4\n\n4= y intercept and -2 equals the slope.

2x-4y=0 is in standard form.  the same equation in slope-intercept form (y=mx+b) is y=1/2x where 1/2 is the slope (y/x or rise over run) and the y-intercept is 0 or at the point (0,0) (because there is no b).  it depends what you want to do with the equation as to what form you put it in.  what do you want to do with it?  what do the directions say?

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

Equation of a line:  y = mx + b\n\nm = 3 (slope)\ny = -4 (y-intercept)\n\ntherefore:  y = 3x - 4 \n\nCrosses x-axis at y = -4 (0,-4)\nCrosses y-axis at x = 4/3 (4/3,0)

4-y-2y=10\n4-3y=10\n-3y=6\ny=-2\n\nx=4-(-2)\nx=6

y = 0.5x-4 \n\nor similarly\n\nx= 2y +8

take - common\n -(y^2-9y+20)\n-(y^2-5y-4y+20)\n-(y(y-5)-4(y-5))\n-(y-4)(y-5)

put -2y=5-3x call it equation {1}\ncall 4x-5y=86 {2}\n\nmultiply all of the terms i {1} by 5\nmultiply all ot the terms in {2) by 2\nthis gives -10y=25-15x {3} &  8x-10y=172 {4}\nyou've got -10y in terms of x in {3}, so just put that into {4}  8x+25-15x=172, -7x=157, \nx = -172/7 sub in to {1} to get y \nman that was ablast from the past, haven't done that for years.

Slope intercept form is y=mx+b\n\nStandard form is Ax+By=C\nIn which A, B, and C are whole numbers.\nSo, you have y-4=-x+1.\ny-4(+4)=-x+1(+4)=\ny=-x+5=\nx+y=5\nThere's your answer.

x+4+x= -20\nFirst collect like terms.\n2x+4= -20\nGet rid of the 4. Subtract 4 to both sides.\n2x+4-4= -20-4\n2x= -24\nIsolate the x. Divide both sides by 2.\n2x/2= -24/2\nx= -12
