The standard formula is y= mx + b your equation is 4x + 3y = -21 so first lets get the y variable by itself and remove the x variable by canceling it out, meaning we are going to subtract 4x + 3y = -21 -4x -4x 3y = -4x - 21 and now we are going to get the y by itself by dividing by 3 ÷3 ÷3 ÷3 y = 1 1/3x -7 that is your answer i hope this helps
