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.
