#x=-5/9#

Explanation:

A zero of a function #f# occurs whenever #f(x)=0#. Here, since #f(x)=9x+5#, this means there is a zero when

#9x+5=0#

Solving this yields

#9x=-5#

#x=-5/9#

If we graph the linear function #f(x)=5x+9#, the graph should cross the #x#-axis at #x=-5/9#, which is the point #(-5/9,0)#.
