Question 1076109
 Graph the line containing the point {{{P}}} and having the slope {{{m}}}. 

{{{P}}}=({{{9}}},{{{-5}}}); 
{{{m=0 }}}

use formula for linear function:

{{{y=mx+b}}}.............since given a point with coordinates ({{{x}}},{{{y}}})=({{{9}}},{{{-5}}}) and slope {{{m=0}}}, we can use it to find {{{b}}}

{{{-5=0*9+b}}}
{{{b=-5}}} and your equation of the line is

{{{y= -5}}} which is horizontal line
