slope: -3/4
explanation: make the equation to “y=mx+b” by subtracting 3x on the other side, giving you the new equation “4y=-3x-4”. then, to get y by itself, divide 4 on both sides, getting the new equation “y=-3/4x-1”. since we know “mx” represents the slope, we now know that the slope is -3/4
let me know if i made a mistake
