Put 3x+12y=-96 into slope intercept form

RideAnS [48]

Answer:

y =-1/4x -8

Step-by-step explanation:

3x+12y=-96

Slope intercept form is y = mx +b where m is the slope and b is the y intercept

Subtract 3x from each side

3x -3x+12y=-3x-96

12y = -3x-96

Divide each side by 12

12y/12 = -3x/12 -96/12

y =-1/4x -8
