Math Problem Statement

Identify an equation in slope-intercept form for the line parallel to y = 5x + 2 that passes through (-6, -1).

Solution

To solve this problem, we need to find an equation of a line that is parallel to y=5x+2y = 5x + 2 and passes through the point (6,1)(-6, -1).

Step-by-Step Solution:

  1. Identify the slope of the given line: The slope-intercept form of a line is y=mx+by = mx + b, where mm is the slope and bb is the y-intercept. From the given equation y=5x+2y = 5x + 2, the slope mm is 5.

  2. Use the fact that parallel lines have the same slope: Since we are looking for a line that is parallel to y=5x+2y = 5x + 2, the slope of the new line must also be m=5m = 5.

  3. Substitute the slope into the slope-intercept form: We now have the equation in the form y=5x+by = 5x + b. The only unknown left is the y-intercept bb.

  4. Use the point (-6, -1) to solve for bb:

    • Substitute x=6x = -6 and y=1y = -1 into the equation: 1=5(6)+b-1 = 5(-6) + b 1=30+b-1 = -30 + b b=29b = 29
  5. Write the equation of the line: Now that we have b=29b = 29, the equation of the line is: y=5x+29y = 5x + 29

Conclusion:

The correct answer is C. y=5x+29y = 5x + 29.

Would you like more details on any step? Here are 5 questions to expand your understanding:

  1. Why do parallel lines have the same slope?
  2. How would you find the equation if the line were perpendicular instead of parallel?
  3. How can we use point-slope form to find the equation of a line?
  4. What happens if the line passed through a different point, like (2,3)(-2, 3)?
  5. How would you graph this equation to verify its correctness?

Tip: Always double-check your work by substituting the point back into the final equation to ensure it's correct!
