6y = 4x^2 y = (4/6)x^2 y = (2/3)x^2 Option B: 2/3
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
The slope of -x plus 6y is equals to 12 is said to be (2 + 1/6x).
(4, -2)
3x + 6y = 12 Rearranging terms: 6y = -3x + 12 Divide through by 6: y = -1/2*x + 2
-6y + 5 = -67y=12-6y = -72-y = -12y = 12
6y = 4x^2 y = (4/6)x^2 y = (2/3)x^2 Option B: 2/3

The slope of -x plus 6y is equals to 12 is said to be (2 + 1/6x).
Yes. 6y = 18x can be cancelled down to y = 3x. If drawn on a graph, the gradient of the straight line at any given point would be 3. The line also crosses the point (0, 0) [the origin]
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
(4, -2)
3x + 6y = 12 Rearranging terms: 6y = -3x + 12 Divide through by 6: y = -1/2*x + 2
[ y = -12 ] is.

Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12
Two ways to see this: 6y=8-9+6y 6y=6y-1 No answer here 6y= 8-(9+6y) 6y+(9+6y)=8 12y+9=8 12y=-1 y= -(1/12) or -0.08333...
