Question 1110331
A( -1, 4 )
B( 3, 1 ) 
Slope = [ change in y ] / [ change in x ]
{{{ m = ( 4 - 1 ) / ( -1 - 3 ) }}}
{{{ m = 3 / (-4) }}}
{{{ m = -3/4 }}}
----------------------
{{{ m }}} is also the slope of any
line parallel to this on
-----------------------------
Use the general point-slope formula
C( 0, -3 )
{{{ ( y -(-3) ) / ( x - 0 ) = -3/4 }}}
{{{ ( y + 3 ) / x = -3/4 }}}
Multiply both sides by {{{ 4x }}}
{{{ 4*( y + 3 ) = -3*x }}}
{{{ y + 3 = (-3/4)*x }}}
{{{ y = (-3/4)*x - 3 }}}
