Question 862339
The slope is ( change in y ) / ( change in x )
{{{ ( 3 - 0 ) / ( -8 - 0 ) = -(3/8 ) }}}
--------------------------------
Then you can use the general point-slope formula
{{{ ( y - 0 ) / ( x - 0 ) = -(3/8) }}}
{{{ y = -(3/8)*x }}}
This is the slope-intercept form
--------------
You can also put it in the standard form:
{{{ y = -(3/8)*x }}}
{{{ 8y = -3x }}}
{{{ 3x + 8y = 0 }}}
