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 = mx + b\nWhere  m is the slope of the line ond\nb is the y intercept

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).

First you have to find the equation of the line that contains these two points (9,1) and (5,5)\nI believe the easiest way to do that is to use slope and y-intercept form (y=mx+b) m= slope and b= y-intercept\n\nto find slope, m = rise/run\nrise = -4\nrun = 4\nrise / run = -1\n\nTo find y-intercept plug in a coordinate pair and use are found slope.( i used 5,5)\ny=mx+b  x= 5 y=5 m=-1 b =?\n5=(-1)(5) +b\n10 = b\n\nSo this is our equation of the two points\ny=-x +10 \n\nNow we can use this equation to find whether  (10,0) is on  the line: Substitute (10,0) and see if the equation is still valid\n\n 0 = (-1)(10) + 10\n 0 = 0 Yes (10,0) is on the same line as the other points

Remeber that perpendicular lines have negative reciprocal slopes, so the slope of the line you are trying to find is 1/3 (that is the negative reciprocal of -3).  You know that the y intercept is 5, remember that slope intercept form is y = mx + b where m is slope and b is y intercept.  You know both of these things now, the m = 1/3 and the b = 5.  Your equation is y = 1/3x + 5.

The slope of y=2/3x - 4 is....?\n\n2/3 right.\n\nThe slope of a line that is perpendicular to that would be....?\n\nThe negative reciprocal of 2/3, which is -3/2, right.\n\nSo if you have the slope of -3/2 and the y-intercept of 3, the equation would be....?\n\ny = mx + b = -3/2 x + 3, very good.

If you are given the slope(m) and a point on the line(x1, y1) you can write the equation of the line.\n\nYou take the y-intercept equation\ny =m*x + b and substitute x1 and y1 for x and y and get\ny1 = m*x1 + b    \nnow solve for b\nb = (y1-m*x1)\nsubstite b = (y1-m*x1) into the y-intercept equation\ny =m*x +(y1-m*x1)\nsubtract y1 from both sides of the equation\ny -y1 = m*x -m*x1\nbecomes the point-slope formula\ny -y1 =m*(x-x1)

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).

the slope will be (0 + 9) / (-8 +7) = 9/-1 = -9 --> m = -9\n\nnow take a point and plug it in to the formula y = mx + b.\n0 = -9(-8) + b ---> b = -72\n\nnow your done. y = -9x - 72

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)

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! :)

The slope is 3 and the y-intercept is -6

The slope should be 3 over 1 or +3(rise over run)and the x and y intercepts would both be 0  (0,0). \n\nThis can be found by using the equation y=mx+b or by using a graphing calculator. The graph of the line in this case crosses exactly where the x-axis and y-axis cross (0,0).

change the equation to slope intercept form\nsolve the equations for y\nx+2y=3\n2y= 3- x\ny= -x/2 + 3/2\nDo the same thing for the other formula\nthe form is\ny = mx + b\nAfter that just plug in numbers for x to get y

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 :)
