How could you write 2x - 3y =9 in slope-intercept form?

This is truly a sad question, what is the school teaching you? To come to the yahoo answers board to get answers.\n\nSlope intercept form is y=mx+b\nWhich means you have to solve for the y variable on one side.\n\nThe manipulation of variables is as follows.\nsubtract 2x from both sides\n\nDivide through both sides by -3\n\nPlace the resulting form into the y = mx + b form

You don't, really.  y =  mx + b is the slope-intercept line equation, where m = slope and b = y-intercept (the place where x = 0).  I guess you could put both equations in this format, draw the resulting lines, and find where they converge (cross).  That would be easy to do on graph paper, but more difficult to show here.\n\nOne of the other ways to solve the equation system is to substitute one variable for the other.  To do this, you'd first need to put one of the equations in a format where a single variable is by itself on one side of the equation, like this:\ny = 2x - 2\n\nThen plug in the value on the right side of that equation instead of y in the first equation:\nx + (2x + 2) = 4\n3x + 2 = 4\n3x = 2\nx = 2/3\n\nThen plug that back into one of the equations and solve for y\n2/3 + y = 4\ny = 10/3\n\nThe point of convergence for the system is (2/3, 10/3)

This is for math right? If so:\n\nThe slope-intercept form is:\n\ny = mx + b\n\ny = value on the y-axis\nm = slope\nx = value on the x-axis\nb = y-axis intercept\n\nThe slope-intercept form gives the equation for a straight line.

First manipulate a little to get everything lined up\n\n3x - 2y = -8\n9x - 3y = -21\n\nNow to cancel out one of the variables.  It's easiest to cancel out x, since 9 is a multiple of 3.  Multiply the 1st equation by -3\n\n-9x + 6y = 24\n9x -3y = -21\n\nNow add the 2 equations together.  The -9x and 9x cancel eachother out and you are left with\n\n6y - 3y = 24 - 21\n3y = 3\n\nFinish solving for y, and then plug that number in for y in either one of the equations above and solve for x. Good luck!

slope is 2,  y intercept is  - 10

4x+2y=8\n\nSubtract the 4x to the other side to get\n\n2y= -4x + 8\n\nDivide the 2 on all sides to get:\n\n2y(/2)= -4x(/2) + 8 ( /2)\n\nYour final answer will be:\n\ny= -2x + 4\n\n4= y intercept and -2 equals the slope.

m = (9-(-1))/(-2-3) = 10/-5 = -2\n\n-1 = -2(3) + b\nb = -1 + 6\nb = 5\n\n\nf(x)= -2x + 5\n\n\nYou got the slope sign reversed.  Be careful about that.  Otherwise, it's correct!

Using pt. slope equation:\n\nY=mX+B where m=slope = 2/3, b=intercept, in this case = 0,\n\nY = 2/3 * x + 0\n\ny=2x/3.\n\n3y=2x\n3y-2x = 0.\n2x-3y=0

The value of y at the y-intercept (b), which is the point at which the line intersects the y-axis, is -9, and the slope (m) is -3. Following, the y=mx+b or slope-intercept form, the equation is y=-3x-9.

1. 4x+3y=4 solve for y, then find slope and y intercept:\n\n4x + 3y = 4\n3y = -4x + 4\ny= -(4/3)x + (4/3)\nY-intercept is 4/3\nSlope is -4/3\n\n2. Write an equation in the form of y=mx+b of the line that is discribed. y intercept is -4 and the line is parallel to the line whose equation is 2x+y=8\n\nThe line whose equation is 2x + y = 8 is written y = -2x + 8 in slope-intercept form.\n\nThe parallel line with y-intercept 4 is:\n\ny = -2x + 4\n\n3. write the point-slope form of the line of the ordered pairs then use the point-slope form of equation (-2,-5) and (6,-5).\n\nThe slope is 0.\n\nThe point-slope form of the line is:\n\ny = 0x -5 = -5\n\n\n4.  Write an equation for each line in point-slope form of equation and slop-int. passing through (-4,2) and perpendicular to the line whose equation is 3x - 2y + -5 = 0\n\nFirst, rewrite 3x - 2y + -5 = 0 as \ny = (3/2)x -(5/2)\nThe perpendicular line has slope -2/3.\n\nThe point-slope form of the line with slope -2/3 passing trhough (-4,2) is:\n\ny - 2 = -(2/3)(x + 4)\n\nThe slope intercept form of the line with slope -2/3 passing trhough (-4,2) is:\n\ny - 2 = -(2/3)x - 8/3\ny = -(2/3)x - 2/3

the answer is letter "C". coz 3(3x+y)=9x+3y.use the distributive property.now do your homework lazy kid!!! j/k!!! lmao!!! =D haha! kidding! hope i helped you somehow!

Slope intercept form:  y=mx+b where m= the slope and b= the y-intercept.\n\ny=2x-4

your answer is incorrect.\n\nthis is the correct answer:\n\n18x+9y=27 ----->  y= -2x+3; intercept at y= 3 and x= 3/2\n\nhow do i get it?\n\nwhen intercept at y, the x value must be zero, so put 0 into x, you get y= -(2 * 0) + 3 = 3\n\nwhen intercept at x, the y value must be 0, so put 0 into y, you get 0 = -2x + 3 -----> -2x = -3 ----> 2x = 3 ----> x= 3/2\n\ni got trouble also when  i was in school but i keep on practising\n\ngood luck

Slope = rise over run\n\nrise is change in y, run is change in x\n\nso rise = 9 - 6 = 3\nrun = -1 - (-3) = 2\n\ntherefore slope = 3/2\n\nSo using the slope intercept form:\n\ny = mx + b\ny = 3/2x + b\n\nwe plug in either point to solve for b (the y-intercept):\n\n6 = (3/2)(-3) + b\n6 = -9/2 + b\nb = 6 + 9/2 = 10.5\n\ny = mx + b where m = 1.5 and b = 10.5\n\ny = 1.5x + 10.5

Easy!\n\n2x+2y=2 \n3x-y=1\n\nTake the second equation and isolate the single "y":\n\n3x - y = 1 becomes 3x - 1 = y (without going into how)\n\nSubstitute "3x - 1" in the first equation so it reads:\n\n2x+2(3x - 1)=2\n\nSimplify:\n\n2x + 6x - 2 = 2\n8x - 2 = 2\n8x = 4\nx = 1/2\n\nEarlier, we saw that y = 3x - 1, so:\n\ny = 3(1/2) - 1\ny = 3/2 - 1\ny = 1/2\n\nThere may be another way (less involved) that I've forgotten, but you can check each of those values for x and y in both equations to make sure they work.
