thanks again everyone. system of graphing x-2y=8 x+y=-1 i say -1,0 , 0,8 am i there..help?

Would you please type your entire math question the way it is presented in your book? Your description is not enough for anyone to answer you correctly. Thanks!

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.

i am pretty sure the answer is y= -1\n\nyou put it in y=m(x-x^1)+y^1\nand then you put (4,-2) in for x^1 and y^1 and the slpe in for m so it would be\ny=1/4(x-4)-2\nand then distribute the 1/4 so it is\n\ny=1/4x-1-2\nsimplify\n\ny=1/4x-3\n\nnow substitute in (8,y) 8 goes in for x\nso it is\n\ny=1/4(8)-3\n\nso y=2-1\ny=-1\n\ni hope that is right and it helps!

-y=2-x\n\ny=x-2\n\nslope is 1\ny intercept is (0,-2)

Joel, you need some help.  This is one of the easiest questions I have ever heard!  You should know this, man!  You're gonna fail your test if you keep cheating on here and don't actually figure out how it works.  Good luck, brotha'\n\nL = -2 or L(x) = -2

I only see equalities... and what are you supposed to do with them?\n\nAssuming you need to graph them, first put them in terms of y:\n1) y = -x + 2\nThis has a slope of -1 (diagonal downward) and a y-intercept of 2.\n\n2) y = -2\nThis has no slope (horizontal line) and goes through the y-intercept of -2.\n\n3) y = x + 2\nThis has a slope of 1 (diagonal upward) and a y-intercept of 2.\n\nThe lines are shown in the attached diagram... Now what do you want to do with them?

Good Evening\n\nI think we've been avoiding this question because we can't graph here... however to get you started, create an x|y chart for each line, plug in a couple of values, and connect the dots  (for a line you only need two points, but some books recommend finding three, so you can verify you didn't make a mistake somewhere)\n\nx+y = 8\nx|y\n----\n4|4\n3|5\n2|6\n\nx - y = -4\nx|y\n0|4\n1|5\n2|6\n\nGraph the two lines, and they should intersect at (2,6) since it appears in both of the charts...\n\n~i~

-x + 2y = 18\n x + 8y = -38\n\nadd up these two lines\n\n0x+ 10y = -20\ny= -20/10 = -2\n\nx + 8(-2) = -38\nx - 16 = -38\n\n\nx=-22\ny=-2

x-4y+4=12\n\nyou want to get it in y= mx + b form \n\nso switch the 4y and the 12 \n\nx + 4 -12 = 4y\nx - 8 = 4y\n\nnow divide by 4\n\n(1/4)x -2 = y\n\nso the slope is 1/4 and it crosses the y axis at -2\n\nsome points are \n(0, -2)\n(-4, -3)\n(-8, -4)\n(4, -1)\n(8, 0)\n(12, 1)\n\nhope this helped\nbest of luck

y=-6\n4x+y=2\n\nsubstitute -6 for Y\n\n4x-6=2\nadd 6 to both sides\n\n4x=8\nDivide both sides by 4\n\n\nx=2\ny=-6 (taken from above)

The graph is a V.  From the 0,0 draw a line with slope = 1 to the right of the y axis and draw a line with slope = -1 to the right of the y axis.  For y<|x|.  All you have to do is shade in the area below the V.  If y>|X|, all you have to do is shade in the area above the V.  Less than, shade below; greater than, shade above.  That should answer all the questions you've submitted.\n\nAnd no, absolute values do not form parabolas.  Some do, not all.  Like y = sqrt[|x-1|].  This forms 2 graphs each going away from each other.\nNice going NerdyKid.  You're not a nerd, you're a dork.

give values of -3,-2,-1,0,1,2,3 to x and find the corresponding values of y\nyou get the ordered pairs\nnow plot

b) Replace y with 0\n(100+x)^0 = 2*100^0\n1 = 2*1\n1 = 2\nThis implies that y cannot be zero.\nc) Replace x with 0.\n(100+0)^y = 2*100^y\n100^y = 2*100^y\n0 = 2*100^y - 100^y\n0 = 100^y\nThis is never true.\nThis implies that x cannot be zero.\na) The graph looks similar to the graph of y = 1/x

Y - Y1 = M(X - X1)\n\nY - 4 = -2(x + 1)\nY - 4 = -2x - 2\n\nY = -2x + 2

y-y^1=m(x-x^2)\ny-8=2(x-(-2)\ny-8=2(x+2)\n A is the correct answer.\ny-8=2x+4\ny=2x+4+8\ny=2x+12 >> y form\n(transpose)\n-2x+y=12\n(if the variable x is negative make it positive)\n-(-2x+y=12) \n2x-y=-12 >> standard form

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 :)
