Let us find the slopes of the two lines
ax+by=c, slope m1 = -a/b
bx-ay=c, slope m2 = b/a
m1*m2 = (-a/b)(b/a) = -1
Therefore the two lines are perpendicular so the answer is D

Answer:
A
Step-by-step explanation:
Machine A pops more popcorn (12.75 vs 10 oz) in less time (3 min vs 4 min), so pops popcorn the fastest.
Machine A pops more popcorn in one minute, on average.
_____
<em>Additional comment</em>
As a practical matter, neither machine may have popped <em>any</em> popcorn in one minute. Generally, one must wait for the cycle to complete. The average overall rate will depend on how quickly each machine can be recycled to produce another batch.
