Help plz.....................

Answer 1

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
