Answer:

y=-3x-13

Explanation:

Slope Intercept Form:

y=mx+b

We already have our mx:

Which is -3

So insert it unto our equation which makes our new equation:

y=-3x+b

To solve for B we need to distribute our m into our x point.

-3(-4-1)

Multiply:

-12-1

Subtract:

B=-13

Insert it into our equation:

y=-3x-13

Hence, our solution is y=-3x-13
