you can use the y=mx+b formula for a line.  \n\ny is the y-coordinate of a point\n\nm is the slope, x is the x-coordinate of a point\n\nb is the y-intercept (where the line touches or intercepts the y-axes).  \n\nsince you know the y intercept of the line (passes through origin, so it's 0), the value of b would be 0 and  you also know the slope of the line, which is two, the equation for the line would look like this.\n\ny=2x + 0 or y=2x\n\na point on the line would have coordinates that would fit the equation ---- y has to be two times x; x has to be 1/2 of y.\n\nhere are some points on this line: (0,0), (1,2), (-1,-2), (2,4), (-2,-4).\n\nhope that helped :)

Another form of the equation is the point-slope form. If you have two points, find the slope.\n\nm = (a2-b2)/(a1-b1) for points (a1,a2) and (b1,b2)\n\n  Then take one point (a1,a2) and plug it into the following:\n\n(y-a2) = m(x-a1)\n\nIt actually turns out to be the slope intercept form, but if your teacher will accept that form than it is easier since you can just leave it like that.

*Note that when the line is vertical the slope is undefined.\nVertical lines have the form x = c.\nTherefore, since this line passes through (2, -3), the x value is 2, and the equation for this line is simply x = 2.\n\nhttp://www.wtamu.edu/academic/anns/mps/math/mathlab/int_algebra/int_alg_tut15_slope.htm\n\nhttp://math.about.com/library/weekly/aa120502a.htm

Yes that will be correct because after you isolate the (y) in other words put it in slope inercect form it would be \ny=2x+4 \nm=2\nb=4

m = 2\nb = 4\n\nThus, your line's equation is y = 2x + 4\n\nThe x-intercept occurs where the line crosses the x-axis, which is also where y = 0. Substituting 0 for y in the above equation:\n\n0 = 2x + 4\n-4 = 2x\n-2 = x (x-intercept)

It all depends on what result you're hoping to get.  For example, if you want to solve a system of equations in two variables, you would try to get the variables on the same side in both equations.  If you want to express the equation in slope intercept form, you would move the y variables to the left side and the x variables and constants to the right side of the equation.  If you're trying to express the equation in standard form, i.e. ax + by + c = 0, you want both variables on the same side.

since the y intercept is 1, put a mark one tick above the origin, then since the slope is -1, put a mark down one and to the right of that one.  then do that a few times to make a line.

Remember the fomula...\n\ny = mx + b\n\nm = Slope\n\nb = Y-intercept\n\nx and y = points\n\nSo plug everything in...\n\n1 = 4(2) + b\nMulitply\n1 = 8 + b\nSubtract 8 on each side\n-7 = b\n\ny = 4x - 7

if the slope is undefined,the line will be parallel to the y axis and of the form x=k\ny-2=1/0(x+3)\n0(y-2)=x=3\nx+3=0\nx=-3

To write this in slope intercept form, we will put it in the form y=mx+b like you said.  \n\ny-6=0\n\nnow we add 6 to both sides and get\ny = 6\n\nFor slope intercept form, I always put the x in there.  No x in the equation is the same as 0x because 0 * x = 0.\n\ny = 0x + 6\n\nThis equation has a slope of 0.\n\nOn this equation, y will be equal to 6 no matter what x is.\n\nLet's do a few points to prove that this will be a horizontal line.\n\n(0,6)\n(1,6)\n(2,6)\n(3,6)\netc...\n\nIf you plot these points, you will see a horizontal line at 6.

A, see 3x+2y=12 in slope-intercept form is "y= -3/2x+6"\nperpendicular lines have slope that are negative reciprocals of each other. Meaning, essentially that you flip the number and change the sign.\nHope it helps..

slope intercept formula is y=mx +b to find b subsitute in for y,m, and x.  so 1 = -2(0) + b.   1 = 0 + b so b = 1 then your equation would be y=-2x + 1.

This is for math right? If so:\n\nThe slope-intercept form is:\n\ny = mx + b\n\ny = value on the y-axis\nm = slope\nx = value on the x-axis\nb = y-axis intercept\n\nThe slope-intercept form gives the equation for a straight line.

A line's equation is y=mx+b where m is the slope of the line and b is where it crosses the y-axis.  In this case, you need to simplify the equation down to make it into the y=mx+b format.  If you do this, you get y=10x-13.  So in this instance, the slope of the line is 10.

y = m (x-x1) + y1\nm=slope (so m=2)\nx1 and y1 are the coordinates. Just plug your numbers in and expand the m(x-x1) part.
