What is the vertical asymptote of 3x-1/2x+9

Question

directrix · Answer

Is this supposed to be an equation? The equation, y = (3x - 1) / (2x + 9) ?

Yeah

anonymous · Answer

Don't I just do 2x+9 = 0 and solve for it?

directrix · Answer

Solve for x in 2x+9 = 0, yes. That will give you the value of x which cause the rational function to be undefined. 

Note: Check to make sure that 2x + 9 and 3x -1 have no common factors.

@Fifi11  Let me know what you get as an answer and I will tell you what I got. Okay?

anonymous · Answer

-9/2s

>>Don't I just do 2x+9 = 0 and solve for it?

2x + 9 = 0

2x + 9 - 9 = 0 - 9

Solve this for x.  -->  @Fifi11   I did not see an "s" in the equation.

anonymous · Answer

Yeah it's -9/2 I meant to say negative nine halfs

directrix · Answer

The vertical asymptote is an equation. So, to call it -9/2 is incorrect.

What is the equation of the vertical asymptote?
