Question

I need help with this problem and to see if I'm doing it right:

For the table, identify the independent and
dependent variables, Represent the relationship
using words, an equation and a graph.


# of cases of | # of bottles
bottled | of water, b
water, c |

1 | 24
2 | 48
5 | 120
10 | 240
20 | 480


So far I think:
Independent Variable is C ( # of cases of bottled water)

Dependent Variable is B ( # of bottles of water)

Because the number of bottles depends on the number of cases

And my thoughts for the equation are:

B = 24C

Thoughts?

Answer 1

looks good

Answer 2

What should the graph look like?

Answer 3

independent is traditionally on x-axis

straight line through the origin
... no cases, no bottles

slope is 24 bottles per case

Answer 4

So do I plot the dots on all of those and then connect the line?

Answer 5

yes

usually, partial cases do exist

Answer 6

4. Graph the function rule. Use labels. Explain why the
graph is continuous or discrete.
The amount of money made by selling bikes depends
on the number n of bikes sold. So a = 150n.

So I need help with how to graph this and I know what discrete and continuous functions are but I don't know how I'd relate them to this equation

Answer 7

It's not possible for tutors on Jiskha to help you with graphing more than Scott has already done.

You should learn to make good use of https://www.khanacademy.org/ Click on the subject and/or topic you need across the top of the webpage or use the Search feature.

I searched for "graphing linear equations" there, and here are the results:
