Line m is perpendicular to line n. Which statement about lines m and n is true?

  see below

Step-by-step explanation:

Slopes of perpendicular lines are negative reciprocals of each other:

  m1 = -1/m2

  (m1)(m2) = -1

So, their product is -1.

Additional comment

The rule above does not apply to horizontal and vertical lines, because the slope of a vertical line is undefined. In this problem, that is not an issue, because the lines are not aligned with the axes.

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
