To determine whether the lines are parallel, perpendicular, or neither, we can compare their slopes. We can rewrite the equations in slope-intercept form (y = mx + b) to find the slopes.

9x + 3y = 12
3y = -9x + 12
y = (-9/3)x + 12/3
y = -3x + 4

15x + 5y = 21
5y = -15x + 21
y = (-15/5)x + 21/5
y = -3x + 21/5

The slopes of both lines are -3, meaning they have the same slope. Therefore, the lines are parallel.

The answer is B) parallel.

To find the average attendance next year, we need to substitute the number of games won this year (w = 93) into the equation A = 30w + 6000:

A = 30(93) + 6000
A = 2790 + 6000
A = 8790

Therefore, the average attendance next year if the team wins 93 games this year will be 8790.

The answer is C) 8790.
