$y = - x - 3$ $y=-x-3$

Explanation:

i am assuming that you are asking for the equation of the line.
$y = m x + c$ $y=mx+c$
$c = s l o p e = - 3$ $c=slope=-3$
subbing in y and x from the given point (2,-1),
$x = 2, y = - 1$ $x=2, y= -1$
will get us
$- 1 = m (2) - 3$ $-1=m(2)-3$
$- 1 + 3 = 2 m$ $-1+3=2m$
$2 m = - 2$ $2m=-2$
$m = - 1$ $m=-1$
therefore, the equation of the line will be $y = - x - 3$ $y=-x-3$
