There are infinite answers because it’s the same line. If u add x on both sides then divide by 2 u will get y=(1/2)x+3. (As for graphing in standard form just put in any value for x and solve for y and that’s one coordinate and do it again for another them draw a line connecting them.) attached I have what the graph should look. (The website I used was Desmos.com in case u ever want to use it)
