Questions & Step-by-Step Solutions

What is the equation of the line parallel to y = 3x + 2 that passes through the point (4, 1)? (2020)
  • Step 1: Identify the slope of the given line y = 3x + 2. The slope (m) is 3.
  • Step 2: Since parallel lines have the same slope, the slope of the new line will also be 3.
  • Step 3: Use the point-slope form of the equation of a line, which is y - y1 = m(x - x1). Here, (x1, y1) is the point (4, 1) and m is 3.
  • Step 4: Substitute the values into the point-slope form: y - 1 = 3(x - 4).
  • Step 5: Simplify the equation. Distribute 3: y - 1 = 3x - 12.
  • Step 6: Add 1 to both sides to isolate y: y = 3x - 12 + 1.
  • Step 7: Combine like terms: y = 3x - 11.
