Question 720609
{{{ 3x + y = 0 }}}
The slope intercept form looks like:
{{{ y = m*x + b }}} where {{{ m }}} is the slope
{{{ 3x + y = 0 }}}
Subtract {{{ 3x }}} from both sides
{{{ y = -3x }}}
This is in the slope-intercept form
Note that {{{ b = 0 }}} and {{{ m = -3 }}}
Here's a plot of the equation:
