Well, first you would need to get y on it's own, as it is in y=mx+b.
How we would do this is dividing by 5.
-3x+5y/5=20/5
We now have -3x+y=4, so we would need y on its own side.
We would do THIS by adding 3x to both sides.
We would end with y=3x+4
We know in the equation y=mx+b, m=slope.
So in the equation y=3x+4, the slope is 3.
