After you've gotten some experience with this type of equation, it'll be easy for you.  
Since 4x-12=0 has only one variable, we can solve for that variable and get a result that is a constant:  4x=12 => x = 3.  Mark x=3 on the horizontal axis and draw a vertical line through it.  That's the graph of 4x-12=0.

well its interesting... in that all you can do is put a point on the number line at the solution. 

to graph on the number plane you would need 2 variables... x and y

so the equation might be

y = 4x - 12

you have 

4x - 12 = 0

which has a solution of x = 3... 

draw a number line and put a dot on 3... 

hope it makes sense

campbell_st · Answer

the problem is 

4x - 12 = 0

is really asking where do y = 0 and y = 4x -12 intersect.... 

perhaps its a typo and you left out the y.
