Question: If two lines are parallel and one line has the equation 2x + 3y = 6, what is the equation of a line parallel to it that passes through the point (1,2)?
Options:
Correct Answer: 2x + 3y = 8
Solution:
The slope of the line 2x + 3y = 6 is -2/3. A line parallel to it will have the same slope. Using point-slope form, the equation becomes 3y - 2 = -2/3(2 - 1), which simplifies to 2x + 3y = 8.
