What is the x-intercept of the line x=3y+7?
438642
x=3y+7\nx=3(0)+7\nx=7\nHope this helps! ^^\nalso the y intercept is like this:\nx=3y+7\n0=3y+7\n-7=3y\n-2.23333...=y

The slope-intercept form for a line is y=mx+b, wherem is the slope and b is the y-intercept. Comparing this form to y=7x+3, you see that m=7 (the slope) and b=3 (the y-intercept).

a) (x+4y)(x+y)=0    x=-y or -4y\n\nb) (2x+y)(x-3y)=0   x=-y/2 or 37\n\nc) (2x-y)(2x-y)=0  x=y/2\n\nd) 4x^2+7xy-2y^2=0\n    (4x-y)(x+2y)=0    x=y/4 or -2y\n\ne) x(5x+y)=0   x=0 or -y/5\n\nf) x(3x-7y)=0   x=0 or 7y/3

to find the y intercepts, let x=0\n=> 91y = 45(0) +12\n=> y = 12/91\n\nto find the x intercepts, let y=0\n=> 91(0) = 45x +12\n=> x = -12/45\n\n\nyour intercepts are (0, 12/91) and (-12/45, 0)

The eqaution of the line is\ny-y1 =m(x-x1)\ny-0 = -3[x-(-4)]\ny-0 = -3(x+4)\ny= -3x-12

Find the X intercept by setting Y = 0\n\nx-2 = 0\nx = 2\n\nFind the Y intercept by setting X = 0\n\ny = 0-2\ny = -2\n\nSo the two points to plot are (0,-2) and (2,0) \nThen connect those points with a line

The slope-intercept form of a line is\ny = mx + b, where m is the slope and b is the y-intercept.

First put the first equation into slope-intercept form or:\n\ny = mx +b\n\nm = slope,  and b = y-intercept\n\n-3x -3y = 2\n+3x        +3x\n\n-3y = 3x + 2\n/-3     /-3\n\ny = -x + 2/3\n\nSo, your slope for the first equation is:\n\nm = -1\n\nTo have a line parallel to the first line, the slopes must equal.\n\n\n\nUse Point-Slope form.\n\ny - y1 = m ( x - x1)\n\nSince you are using the point (-3, -4)\n\ny1 = -4\n\nx1 = -3\n\nSo your new equation will be:\n\ny - -4 = -1 ( x - -3)\n\n(remember the slope must be the same)\n(a minus a negative = a positive)\ny + 4 = -1(x + 3)\n\ny +4 = -x -3\n   -4         -4\n\ny = -x -7\n\nor you can put it back into standard form ( Ax + By = C)\n\nx + y = -7

The y-intercept is where X=0\n\nAny algebraic equation makes this process simple\n\nFor Example.\n\ny=982372987239487x+z\n\nthe y-intercept is always equal to z no matter what interger is place as a factor of x

All equations for a line will have the form:\n\ny = mx + b,\n\nwhere x & y are coordinates, m is your slope, and b is your y-intercept.\n\nTherefore, substituting in your slope and y intercept, you get:\n\ny = -2/3x + 4\n\nThis equation can then be used to graph the line, since given any x, the corresponding y can be found. :)

The Y-INTERCEPT of the line y = b is b.\n\nFor a y-intercept, you plug in 0 for the other variable, primarily x, but in this case, b.\n\nTherefore, if you plug it in, you receive:\n\ny = 0\n0 = 0\n\nThe y-intercept is 0\n\nPerhaps you should check by graphing, but I assure you that I am correct

You can't really answer that question the way it was asked.  If you know a value of x or y, you can find the other value though.\n\nFor example, say you want to find the x-intercept (where y=0)\n\ny = 3x + 2\n0 = 3x + 2\n-2 = 3x\n-2/3 = x\n\nThere you go, you can do this for any point you know is on the line.

x(y-1) = 2y + 3\n\nxy - x = 2y + 3\nxy - 2y = x + 3\n(x - 2) = (x + 3) / y\n y = (x + 3) / (x -2)

Intercept :  The coordinate of a point at which a line, curve, or surface intersects a coordinate axis.\n So to find X-intercept the line has to intersect the y coordinate axis.therefore put y=0 in the given equation. So\n\n6x-3*0=18\nSo 6x=18\nand So x=18/6\n\nTherefore the result is : x=3\n\nX-intercept is 3

y = (x+3)(x-1)(x-2) = x^3 - 7x + 6

There is no solution:\n\n6x+7y=7\nMultiply by 2\n12x+14y=14\n\nBut we already have\n12x+14y=5\n\n14 does not equal 5, so there are no common solutions.  What does this mean?  They are parallel lines.\n\nWe can do more:  We can tell the y-intercepts of the lines as well. \n\n6x+7y=7\n7y=7\ny=1\n\n12x+14y=5\n14y=5\ny=5/14\n\nThis means that when the graph of 6x+7y=7 is shifted down 9/14, and then it is the same graph of 12x+14y=5\n\nHope this helps!

Basically, its a straight line going through (1,3), with gradient, m=-3. we have y=mx+c. putting the point (1,3) into here, \n\n3=(-3)(1)+c, so c=6, which is the y-intercept. so the line equation is,\n\ny=-3x + 6, which is a straight line with y-intercept at y=6. the line will be sloping downwards since the gradient (m) is negative. if you plot a few values of x and y which satisfy the equation you can see the line. to check axis intercepts, put y=0 for the x-intercept and x=0 for the y-intercept.
