Question: find the slope of a line parallel to the line whose equation is 3y - 6x = 12?
Answer: First subtract 6x on both sides to get 3y = –6x + 12. Then divide each term by 3 to get y = –2x + 4. In the form y = mx + b, m represents the slope. So the coefficient of the x term is the slope, and –2 is the correct answer.
