Best ResponseYou've already chosen the best response.0first we need to find the slope in the original equation because parallel lines have the same slope. We will put the equation in y = mx + b form where m is your slope. 12x + 3y = 23  add 12x to both sides 3y = 12x + 23  now divide both sides by 3 y = 4x + 23/3 now the number in the m position, the slope, is 4 Our parallel line will have a slope of 4. Now we will use y = mx + b again... slope(m) = 4 (2,3)...x = 2 and y = 3 and since we have our slope and our points (x,y), we just need to find b, the y intercept. now we sub 3 = 4(2) + b 3 = 8 + b 83 = b 11 = b so your parallel equation is : y = 4x + (11) or y = 4x  11 questions ?
