the slope of a line is 2 and the y-intercept is 4.  What is the x-intercept?

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 refers to the slope of a line and the y-intercept.

y = mx + b is the slope intercept form, where m = slope\n\nso 2 is the slope in your example\n\nWith any equation for a line, there are 2 variables, x and y, representing the position on the x and y axis.  Given any line equation, you can manipulate it to get it into slope intercept form (y = mx + b), and m will be your slope.\n\nThe y-intercept is where the line crosses the y-axis (or where x = 0).  As you can see, if you put x = 0 in the equation, you will get:\n\ny = 0x + b\ny = b\n\nso when x = 0, y = b.\n\nHope this helps! :)

y=mx+b\n2=2(3)+b..... (in this you know the slope is 2 b/c the line is parallel.\n2=6+b\n-4=b...... (so now you will want to write your equation for your line)\n\ny=2x-4..... (DONE!)

M is the slope which you get by subtracting y coordinates and x coordinates IN THE SAME ORDER, and then dividing.  In your first example, change in y is 6-4 = 2, change in x is 0.5-0 = 0.5.  Then divide change in y by change in x, 2 by 0.5, to get M = 4.  \n\nThen pick one of the points, say the second.  y - 4 = 4(x - 0).  Then do just a little algebra.\ny - 4 = 4(x - 0)\ny = 4x + 4.\n\nSome special cases.  Your 2nd pair have the same x coordinate, so the line is vertical, and the equation is x = 6.  In your 3rd pair the y coordinates are the same so the line is horizontal, y = 2.\n\nSince the slope is a fraction, change in y over change in x, you need to be able to do fraction arithmetic.

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

One way to write the equation of a line is\ny - y1 = m(x - x1)\nwhere m is the slope and (x1, y1) is a point on the line.\n\nGiven your information,\ny - 4 = -2(x - 1)\nThat is the point-slope form of the line.  This can be changed to slope-intercept form:\ny - 4 = -2x + 2\ny = 2x + 6

The equation of a line in slope-intercept form is given by \ny=mx+b where m is the slope and b is the y-intercept.\nAll you have to do is plug the numbers in.\nso the equation is y=9x-3

y - y value.\nx - x value.\nm - slope of line.\nc - line intercept.\n\nSlope = -½\n pt(-2,4)\n y = mx + c\n 4 = m(-2) + c\n 4 = -2m + c\n 4 = -2(-½) + c\n 4 = +1 + c\n 3 = + c\n\n y = mx + c\n y = -½x + 3

To find the slope, you always have to set the equation as y=mx+b.  That equation is called the slope-intercept form.  "m" is the slope and b is the y-intercept.\nNow, to find the slope, try to get y alone.\n1. Subtract 2x from both sides.  You'll get: -8y=-2x+7\n2. Divide both sides by -8.  You'll get: y=(1/4)x+(-7/8)\nSo, the equation is y=(1/4)x-(7/8) and the slope is (1/4).

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. :)

If X=0, then Y=5 (Y-intercept is 5)\nIf Y=0, then X=3\n\nPlot and you get, Slope = rise(y)/run(x) = 5/3

Yeah, make them graphable on your calc.\n\ny = 4-x\ny = 2x-2\n\nIf you want to solve, just set 4-x and 2x-2 equal to each other (since y must also be equal in both equations)\n\n4-x=2x-2\n3x=6\nx=2\n\n\n2+y=4\ny=2\n\nTheir intersection is (2,2)\n\nThe y-intercept of the first is 4, and the second is 2.\nThe slope for the first is -1, and the second is 2.\nThe x-intercept of the first is 4, and the second is 1.

well, you really should do your own homework, but the answer is D. substitute 3 and 7 into the equation for the easy answer.......7=2(3)+1......but to know that, the equation is  y = mx + b. m designates the slope of the line, and b the y-intercept, that is b is the second coordinate of the point where the line crosses the y-axis

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?

the slope is 4\nwhen an equation is in standard form:\ny=mx+b\nm (which is the coefficient of x) is the slope

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)
