The lines representing the pair of equations 9x + 3y + 12 = 0 and 18x ...
Explanation:
To determine the position of the given pair of equations, we can convert them into slope-intercept form (y=mx+c), where m is the slope and c is the y-intercept.

9x - 3y + 12 = 0
-3y = -9x - 12
y = 3x + 4

18x - 6y + 24 = 0
-6y = -18x - 24
y = 3x + 4

As we can see, both equations have the same slope (m=3) and y-intercept (c=4). This means that the lines are parallel to each other, because they have the same steepness and will never intersect.

Therefore, the correct answer is option B - the lines representing the pair of equations are parallel.
