A straight line with slope 5 contains the points (3,4) and (2, k).  Find the value of k..?
450157
slope = (y2-y1)/(x2-x1)\n5= (k-4)/(2-3)\n5= (k-4)/(-1)\nk-4= (-1)*5\nk-4= -5\nk= 4-5\nso k= -1.\ni hope you understand they way I worked it out. If you have any more questions, pls feel free to ask me on: pinkieflava@yahoo.co.uk

Sounds like you need homework help.  Why don't you just post the whole problem?\n\nWhen working with slope, remember to put it in fraction form if it isn't already.  For example a slope of 5 would be the same as a slope of 5/1.  Now, learn the phrase "up and right" because that is how you read slope.  If your slope is 5/1, then from any point on the line, you move up 5 units and right 1 unit to draw the line.  \n\nIf your slope is -3/2 you would move up -3 units (which is the same as down 3) and right 2 units.   If your slope was 9/-7 you would move up 9 units and right -7 units (which is the same as left 7).  Get it?\n\nSo now, back to your question...  One way to write an equation for a line is y=mx+b.  You gave us B, so we know it is y=mx+1/3.  But you didn't give enough information.  \n\nIf that was a mistake and m is supposed to equal 1, then the fraction would be 1/1, and the line would move up 1, right1.  That line would look like it goes up and to the right, in the center at a diagonal straight through the upper right quadrant.\n\nHope that helps

for (0,2),(4,0) the slope is -1/2\nfor (-2,0),(4,0) the slope is 0

Y=MX+B\nso identify which number is next to the X, that will be your slope.  The other number is the Y-intercept.\n\nFirst problem:\nY=-2X+3\nthe -2 is next to the X so it is the slope (M)\nthe 3 is by itself so it is the Y-intercept (B)\nthe other two problems are the same way

If you put an equation in the form:\n\ny = m*x + b\n\nthen, \n\nm = the slope\nb = the y-intercept.\n\nIf you look for a parallel line that passes through a given point, then you keep the slope the same, and solve for the slope:\n\n5x-4y = 1   -->  y = 5/4x - 1/4\nthe family of all parallel lines is\ny = 5/4x + b  (for any value of b).\n\nFor a line passing through (-8, 2), plug the numbers in and solve for b:\n2 = 5/4*(-8) + b\nb = 12\n\nSo y = 5/4x+12 is a line with slope 5/4, passing through the point (-8,2).

If you mean parallel to y=2x + 5, then the slope will be 2\n\nSo you need to use:\ny = 2x + b\n\nPlug in your point (-1, 4) and solve for b:\n4 = 2(-1) + b\n4 = -2 + b\nb = 6\n\nSo your line is:\ny = 2x + 6

Slope is defined as increase in y over increase in x,\n\nIncrease in y is 5-2=3\nIncrease in x is -3/4-5/4=-0.5\nSo slope is 3/(-0.5)=-3/2

Find the slope of the line that connects those points.

The general purpose straight line has the equation Y = mX.  If you know the slope (m) to get the equation of a line thru a given point, say (h,k) just substitute the slope for the m, (X-h) for the X, and (Y-k) for the Y.  E.g. a line with slope 2 thru (-5,7) has the equation (Y-7)=2(X+5).  Then do a little algebra to get the slope-intercept form;\nY=2X+17.\n\nIf slope is not given, but instead you have coordinates of two points, find the slope by dividing the difference between the Y coordinates of the points by that between the X coordinates.  It doesn't matter which point you subtract, as long as you do it the same way for both the X and Y coordinates.   Then use that slope with the coordinates of either one of the points as above to get the equation.\n\nIn the example given, you're apparently supposed to find a line thru (5,1) that intercepts the line Y=4X-7.  Any two lines will intercept somewhere, so two quick answers are X=5 or Y=-7!  You can substitute X=5 into the equation to get the point of intersection of the first: (5,13).  OR\n\nA line thru (5,1) parallel to the line y=4X-7 will have the same slope.  So its equation will be (Y-1)=4(X-5) or \nY=4X-19.\n\nA line thru (5,1) and perpendicular to the line y=4X-7 will have a slope that is the negative reciprocal of 4 = -1/4 or -0.25.  So its equation will be (Y-1)=(-0.25)(X-5) which simplifies to Y = -0.25X + 1.25 + 1 or Y = -0.25X + 2.25.\n\nThink about it.  Thinking always helps.  Yahoo won't be there for your tests.

u are talking about a st line with slope =1??\ni.e\nx-a=y-b\ny=x+b-a\nhere k decides slope\nsince both have same k\ntherefore slope=1\nthanks

if a line has the equation px+qy=r\nthen the slope of the line is -q/p

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!)

Use the formula m = (y2-y1) / (x2-x1) to answer this.  (x1,y1) and (x2,y2) are your two points.\n\nm = (4-4) / (7-1) = 0/6 = 0\n\nSo, your slope is 0.\n\n(All lines with a slope of 0 are lines that are parallel to the x-axis)

50 because if you rearrange it in the format of y=mx+b with m being the slope it would equal to 50 in your case

x:y=5:3=k,then x=5k,y=3k\n5x+3y=5*5k+3*3k=34k,3x+5y=15k+15k=30k\nso the answer is 34k/30k=17/15 (k<>0)
