Slope and y-intercept?
967269
1. Since 5y = 15x + 35, y = 3x + 7, and the slope is 3.\n\n2. Since 3x + y = 7, y = -3x + 7, and the slope is -3.

Answer:\nIf the slopes are the same but the y-intercepts are different then the lines are different. (Also, if the y-intercepts are the same but the slopes are different then the lines are different).\n\nExplanation:\nIf you have the two equations in the slope-intercept form (y=mx+b):\n\nLine 1: y'=m'x'+b'\nLine 2: y"=m"x"+b"\n\nThen,\na) If m'=m", then the lines are parallel.\nb) If b'=b", then the lines intercept the y-axis at the same point.\nc) If m'=m" AND b'=b" then the lines are parallel AND they intercept the y-axis at the same point. In this case, if you look at the two equations, you will see that the two equations are identical - this means that the two lines are identical. Line1 = Line2.\n\nHere's an illustration of the concept:\nhttp://i36.photobucket.com/albums/e49/UKild/SameAndDifferentSlopes.jpg

x=-3 is the equation for the line.\n\ny=mx+b where m is slope and b is y-intercept.\n\nm=change in y/change in x= [(-3)-1]/[(-3)-(-3)]\nm=-4/0\nWhen you divide by zero the answer is undefined, so slope is undefined.\n\nOnly vertical lines have undefined slopes, so the equation for the line is x=-3. This means that no matter what value you pick for y, x will be equal to -3.

Write the equation in the point-slope form, then substitute 0 for x and solve for y.  That is the y-intercept.

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.

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

First, the slope is (delta y)/(delta X) = (-3)/2) = -3/2\n\nthe y intercept is +6  (interpolating back from \n(6,-3) ,(4,0),(2,3), (0,6)\n\nso the equation is Y=-3/2 X + 6\n\ngo from there and you have your answer.

this is the slope intercept form equation\n\ny=mx + b\n\nwhere m is the slope and b is where the line crosses the y axis\n\nfor example\n\ny= 1/2x + 2

y-intercept occurs when x=0\n\nSo, set x=0, and your equation becomes:\n    2(0) - y = 4\n\nor, because 2*0 = 0,\n    \n    y = -4 is your y-intercept.\n\nThe slope can be found by writing the equation in standard "y = mx + b" form, where "m" is the slope. In your example, that would be:\n\n    y = 2x - 4\n\nSo, the slope ("m") is 2.\n\nDone and done.

if it is parallel the slope is 3 so the equation is\ny = 3x + b\nnow you just solve\n-2 = 3*2 + b\n\nfor b and that is your new y intercept and equation.

Remember the slope-intercept form?\n\ny = mx + b.\n\ny = the y coordinate.\nx = the x coordinate.\nm = the slope.\nb = the y - intercept.\n\nyour equation is already in slope-intercept form. so all you need to do is match up your numbers with the y = mx + b.\n\nThe slope is -5.\nThe y - intercept is -17.\n\nHope that helps :)

Equation/Formula for Point slope equation is y = mx + b wherein b is the y intercept and m is the slope.\n\n1. y intercept = -3\n    slope = 4\n\n2. y intercept = 4\n    slope = -3\n\n3. y intercept = 0\n    slope = 3\n\n4. you must simplify this one. The solution is:\n\n(step by step)\n\nIsolate the y     4/5y = -1/2x + 1\ncancel the fraction beside y  (5/4)4/5y = -1/2x(5/4) + 1 (5/4)\nand then it becomes    y = -5/8x + 1 1/4\n\nso then the y intercept is = 1 1/4 (--one and one over four)\nand the slope is = -5/8\n\n*when looking for the slope, do not inclued the variable "x" in your answer :)\n\nI hope this helped :)

iso late the y by subtracting 6x from each side, so you are left with 2y = 9-6x, then divide each side by the coefficient of y (2) making your equation: y=9/2-3x...the y intercept of the line is 9/2 and the slope is -3 (so start at the point on the graph 9/2, then move 3 squares down, and over to the right one)

sure...here are 2\n\nThe slope-intercept equation for a line\ny = mx + b\ny=the y part of a point given any x value\nm=slope of the line\nx=the x part of the point given y, or just given x to find y\nb=y intercept, the point at which the line crosses teh y axis, or (0,y)\n\nanother equation is\nPythagorean Theorem \na^2 +b^2 = c^2\na, b, c are sides of a triangle, c is the longest side (the hypotenuse)\nthis formula only works in right triangles\n\nhope this helps\nmatttlocke
