How could you write this equation in slope-intercept form ? 6x + 9y = 27?

The slope intercept form is y=mx+b. Basically, you solve for y. For your formula, you would do the following.\n\n6x + 9y = 27   (Simplify by dividing by 3)\n2x + 3y = 9    (Move x to right side of equation)\n2x - 2x + 3y = -2x + 9 (Simplify)\n3y = -2x + 9   ( Divide by 3 to solve for y)\n3y/3 = (-2/3)x + 9/3 (Simplify)\ny = (-2/3)x + 3\n\nThe (-2/3) is a negative two thirds. I just couldn't put that in this little box.

x - 3y = 9\n\nTo solve for "y" you have to isolate it on one side of the equation. First subtract x from both sides to get: \n\n-3y = 9 - x\n\nthen divide both sides by -3 to get:\n\ny = (9 - x) / -3  \n\nWhich is y = -3 + 1/3 x or in slope-intercept form: \n\ny = 1/3 x -3 \n\n\nNow graph the y-intercept at -3 and use the slope (go 1 up + 3 across) to get the next point and so forth. \n\nHope this helps...Good luck! =)

in an equation y = mx + b, m is always the slope and by is always the y-intercept\n\nx + 2y = 3\n2y = 3 - x\ny = (-1/2)x + (3/2)\nthe slope is -1/2 and the y-intercept is 3/2\n\n1/2x - 9 = 0\nwhere's the y?  this isnt an equation\n\ny = 3x - 2\nthe slope is 3 and the y-intercept is -2\n\ny + 4x = 8\ny = -4x + 8\nthe slope is -4 and the y-intercept is 8

Standard form for a slope intercept equation is:\n\ny = mx + b\n\nwhere m is the slope and b is the y-intercept.  So, transforming:\n7x + 4y = 20\n4y = 20 - 7x\ny = (20 - 7x) / 4\ny = 5 - 7/4 x\ny = -7/4 x + 5\n\nAnd\n5x + 6y = 19\n6y = 19 - 5x\ny = (19-5x) / 6\ny = 19/6 - 5/6 x\ny = -5/6 x + 19/6

We'll use the "addition" (or "elimination") method, but if we were to use the substitution method, we'd get the same result.\n\nIf you multiply both sides of the first equation by 3, you'll get:\n\n9x - 9y = 27\n\nAdding the two equations together then produces:\n\n9x - 9y - 9x + 9y = 27 - 25\n\nWhen you combine like terms, you get\n\n0 = 2\n\nNow, obviously, that's not true, which means this is an "inconsistent system" -- a system without any solutions.\n\nHope that helps!

9y=11-x\n9y=11-(y+3) , replace x, since x=y+3\n10y=8       , +x to both sides, 8=11-3\ny=4/5       , divide both sized by 10, \nx=19/5      , x=(4/5)+3

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 :)

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

An equation in slope-intercept form is y = mx + b\nIn the equation, m = slope and b = y-intercept\n\nUsing the equation given\ny=-3/2x+6\ny = mx + b\n\nWe know that the slope is -3/2.  That would be m.\nWe know the y-intercept is 6.  That would be b.\n\nNow we have to find the x-intercept.\n\nTo get the x-intercept, we will set y = 0 and solve the equation for x.\ny=-3/2x+6\nSubstitute 0 for y\n0=-3/2x+6\nAdd 3/2x to both sides\n3/2x = 6\nMultiply both sides by 2/3\n2/3*3/2x = 6*2/3\nx = 4\nThe x-intercept is 4.\n\nSlope =  -3/2. \ny-intercept = 6.\nx-intercept = 4.

y+3 = (-8/3)(x-3)\ny = (-8/3)(x-3) - 3\ny = (-8/3)x + 8 - 3\nTherefore, y = (-8/3)x + 5 would be the equation satisfying the mentioned conditions in slope-intercept form.

First you have to find the equation of the line that contains these two points (9,1) and (5,5)\nI believe the easiest way to do that is to use slope and y-intercept form (y=mx+b) m= slope and b= y-intercept\n\nto find slope, m = rise/run\nrise = -4\nrun = 4\nrise / run = -1\n\nTo find y-intercept plug in a coordinate pair and use are found slope.( i used 5,5)\ny=mx+b  x= 5 y=5 m=-1 b =?\n5=(-1)(5) +b\n10 = b\n\nSo this is our equation of the two points\ny=-x +10 \n\nNow we can use this equation to find whether  (10,0) is on  the line: Substitute (10,0) and see if the equation is still valid\n\n 0 = (-1)(10) + 10\n 0 = 0 Yes (10,0) is on the same line as the other points

8y=-23-x\n\n-5x+8y=19\n-5x+(-23-x)=19\n-6x-23=19\n-6x=42\nx=-7\n\n-7+8y=-23\n8y=-16\ny=-2\n\n\nThe solution is (-7,-2).  I've checked it, so it works.  However, it is a good idea to always check the solutions.  Since you end up using only one equation to find the second variable, make sure the pair also works in the second equation.\n\nHope this helps!

Use the slope-intercept formula to get the equation of the line.\n\ny = mx + b\nm = slope\nb = y-intercept\n\nStick the slope of 24 in for the m.\nStick the y-intercept of 4 into b.\n\ny = 24x + 4

Start with \n\n    4x + 9y = 24\n\nsubstitute the value of y from the second equation:\n\n    4x + 9(-x/3 + 2) = 24\n--> 4x -3x + 18 = 24\n--> x = 24 - 18\n--> x = 6\n\nand now y can be computed,\n\n    y = -6/3 + 2\n--> y = 0
