Explanation: the standard form of an equation is written as Ax + By = C, where A, B, and C are integers. first, distribute -3: y + 4 = -3x - 3 then get x and y on the same side and the number on the other side for standard form. add 3 to both sides: y + 7 = -3x subtract y from both sides: 7 = -3x - y
