what is the slope of the line that has the equation 4x+2y=12?

-2

4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2

4x+2y = 12 2y = -4x+12 y = -2x+6 So the y intercept is 6 and the slope is -2

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.

2y = 4x + 4y = 2x + 2

2y-4x = -12 2y = 4x-12 y = 2x-6 So the y intercept is -6

I guess you mean 4x + 2y = 12 is changed to 4x + 2y = 36. The graph is translated (shifted) up the 7 axis by 24.

4x+2y = 20 2y = -4x+20 y = -2x+10

4x-2y = 12 -2y = -4x+12 y = 2x-6 Therefore the y intercept is -6 and the slope is 2

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

8x+2y=4x=-y/4+0.5y=-4x+2

x = 11/7 and y = 12/7

2y - 4x = -12 2y = 4x - 12 At the x-intercept, y = 0. 0 = 4x - 12 0 = x - 3 x = 3

-4x-2y = 3 -2y = 4x+3 y = -2x-1.5 which is the equation of a straight line

3+4x=2y-9 Convert to standard form: 2y = 4x+12 or y = 2x+6 The slope, then, is the coefficient of x ie 2.

No.

4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists

4x-2y+3x+2y When simplified: 7x

4x+2y = 6 2y = -4x+6 y = -2x+3 Slope = -2

4x+2y-8=0 2y=8-4x y=4-2x slope= -2

-6
