Question

Which graph represents viable values for y = 2x, where x is the number of pounds of rice scooped and purchased from a bulk bin at the grocery store and y is the total cost of the rice?

Answer 1

Thank you for asking this question:

here is your answer:

This is a direct variation problem. A relation between two variables which is y is directly proportional to x.

In this situation we need to put some values for our  x(pounds of rice) to get the value of our y (cost per pound of rice). To make it easier we will make a table.  

x pounds of rice                   1      2      3      4

y cost of rice per pound      2    4       6      8
