Question 1057315
{{{ y = 0 }}} is the x-axis
so, the line you need nust be horizontal
( the slope, {{{ m }}} is zero )
-----------------
{{{ y = m*x + b }}}
{{{ m = 0 }}}
{{{ y = 0*x + b }}}
{{{ y = b }}}
------------------
The line must go through ( 2, -5 ) 
Plug this point into {{{ y = b }}}
{{{ -5 = b }}}, so now you have:
{{{ y = -5 }}}
( note that this is a horizontal line, the same as the x-axis )
