Answer
$y=-2x-1$
Work Step by Step
The given line has a slope of -2 and goes through the point (1,-3).
We can write this line in point-slope form $y-y_{1}=m(x-x_{1})$ with $m=-2$ and $(x_{1},y_{1})=(1,-3)$.
$y+3=-2(x-1)=-2x+2$
Subtract 3 from both sides.
$y=-2x-1$
This line is now in the slope-intercept form of $y=mx+b$.
