Question 1067114
{{{ y = 7 }}} is a horizontal line through ( 0, 7 )
-----------------------
The slope of a horizontal line is zero
( 2, 4 )
Use the general point-slope formula:
{{{ ( y - 4 ) / ( x - 2 ) = 0 }}}
{{{ y - 4 = 0*( x - 2 ) }}}
{{{ y - 4 = 0 }}}
{{{ y = 4 }}}
Notice {{{ y = 4 }}} is also a horizontal line
and it goes through ( 0, 4 )
