Question 945565

For a line that is parallel to the x-axis, the equation for such a line is:

          {{{y = b }}}     where {{{b}}} is some constant 

if a line containing the point ({{{2}}},{{{7}}}), as you can see {{{y}}} coordinate of the point is {{{7}}}, and the equation for a line that is parallel to the x-axis and containing given point is 

{{{y=7}}}
