in point slope form, which is generally:
m(x-x1)=y-y1
plugging in:
-3(x+2) = y+1
in slope intercept form,
-3x-6=y+1
y=-3x-7

It is very easy. The equation may have the form y-y1=m(x- x1) where m is the slope and (x1,y1) the point. You have just to put the number there: y +1 = -3(x+2) and you have the equation. You may change the form to y = -3x -3 if you want, but it is not necessary.

y+1=-3(x+2)
y+1=-3x-6
3x+y+7=0
