Scenario:
A stack of n small cups has a height, h, in centimeters of h=1.5n+6.
A stack of n large cups has a height, h, in centimeters of h=1.5n+9.

Using G00gle Draw, or by hand, graph the equations for each cup on the same set of axes. Make sure to label the axes and decide on an appropriate scale.

For what number of cups will the two stacks have the same height?

Answers

Answer:

The lines will never intersect.

Step-by-step explanation:

The slope of the cups is the same, 1.5.  The y-intercept of the small cups is 6

The y-intercept of the big cups is 9.

This means that the lines will never intersect because they are parallel lines and have the same slope but different y-intercepts.
