How to find the vertical asymptote of a function without a denominator?
Galina-37 [17]
Let's consider the equation; 

7x+2=y <-- no denominator present

If you look at the graph, you will also notice that there are no possible values of x that cannot be represented through this graph. There will always be a corresponding y coordinate. 

This can be applied to a wide range of equations where no denominator with an x value will have a vertical asymptote. Try to visualize a simpler situation with the same qualities if you don't know how to find the solution. 

Hope I helped :)
