Answer:

A

Explanation:

Remark

The trick here is convert what you have to Ax + By = C

Solution

Given

y - 3 = 1/2 ( x + 6) Multiply both sides by 2

Solve

  • 2(y - 3) = 2 * 1/2 (x + 6) Do the multiplication
  • 2(y - 3) = x + 6 Remove the brackets
  • 2y - 6 = x + 6 Add 6 to both sides.
  • 2y - 6 + 6 = x + 6 + 6 Combine
  • 2y = x + 12 Subtract x from both sides.
  • -x + 2y = x - x + 12 Combine
  • -x + 2y = 12

Answer

  • A = - 1
  • B = 2
  • C = 12

or

  • When you multiply through by - 1 you get x - 2y = - 12 which is A
