Choose the correct answer. The slope of the graph of 3x + 6y = 12 is ____. A) -3/6 B) 6/12 C) 6/3 D) 3/12

13. Choose the correct answer.
The slope of the graph of 3x + 6y = 12 is ____.
A) -3/6
B) 6/12
C) 6/3
D) 3/12

Answer

To find the slope of the equation 3x + 6y = 12, we need to rewrite it in the slope-intercept form y = mx + b, where m is the slope.

  1. Start with the equation: 3x + 6y = 12
  2. Subtract 3x from both sides: 6y = -3x + 12
  3. Divide every term by 6: y = (-3/6)x + 2
  4. The slope (m) is -3/6, which simplifies to -1/2.

The correct answer is A) -3/6.
