what is the slope of the line that has the equation 4x+2y=12?
The equation is -2y + 16 = 10
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
3x + 2y = 8 This is an equation. It could be the equation of a line.
4y + 4 = 2y + 12Subtract 2y from each side of the equation:2y + 4 = 12Subtract 4 from each side:2y = 8Divide each side by 2:y = 4
If: -3x+2y = 12 Then: y = 1.5x+6 in slope-intercept form
2x+y=-12-4x-2y=30 x=-y/2+30, you plug this into -12-4x-2y=30 and get -12+2y-120-2y=30 which gives 2y-2y=162. This is not possible, so the equation is unsolvable.
42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
-3x+2y = 12 2y = 3x+12 y = 1.5x+6 So the slope is 1.5 and the y intercept is 6
7x = -3y + 12
4x + 2y = 12 3x - 2y = 9 Have to use simultaneous equations, so add together to get : 7x = 21 so x = 3 Put it into any part of the equation 4x3 + 2y = 12 12 + 2y = 12 2y = 0 y = 0, x = 3
