Answer: 2 x + y = − 3 Explanation: Standard Form for writing down a Linear Equation is: A x + B y = C A shouldn't be negative, A and B shouldn't both be zero, and A , B and C should be integers. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ y = 2 x − 3 to standard form: Bring 2x to the left side -2x-y=3 Multiply all by -1 I Remember! I I A mustn't be negative 2 x + y = − 3
