Questions & Step-by-Step Solutions

If the line 3x - 4y + 12 = 0 is parallel to another line, what is the slope of that line?
Correct Answer: 3/4
  • Step 1: Identify the equation of the line given, which is 3x - 4y + 12 = 0.
  • Step 2: Rewrite the equation in slope-intercept form (y = mx + b) to find the slope. Start by isolating y.
  • Step 3: Move 3x and 12 to the other side: -4y = -3x - 12.
  • Step 4: Divide every term by -4 to solve for y: y = (3/4)x + 3.
  • Step 5: Identify the slope (m) from the equation y = (3/4)x + 3, which is 3/4.
  • Step 6: Remember that parallel lines have the same slope, so the slope of the parallel line is also 3/4.
