Answer:

See a solution process below:

Explanation:

The line #x = -9# is a vertical line where for each and every value of #y#, #x# will equal #-9#.

By definition, the slope of a vertical line is undefined.

because this is a vertical line at the #-9# point on the #x#-axis, there will be no y-intercept.

The #x# intercept will be: #(-9,0)#.
