The gradient of the graph of 3y=6x-12

We first need to rearrange the equation into the form y = mx + c, where m is the gradient:

3y = 6x - 12
y = (6/3)x - 12/3
y = 2x - 4

Now we can see that the gradient is 2, because the coefficient of x is 2. Therefore, the gradient of the graph of 3y=6x-12 is 2.
