$y=-1/3x-1/3$

The equation of a line can be expressed as

$y=mx+b$

You are given

$y=-1$

$x=2$

$m=-1/3$

Plugging each of these into the equation of a line gives us

$-1=-1/3 (2)+b$

$-1+2/3=b$

$b=-1/3$

Finally, rewrite the linear equation with slope, $m$ , and slope intercept $b$ .

$y=-1/3x-1/3$
