Question

Which of the following equations could be used to show the relationship between number of days and amount of soda consumed? Select all that apply. Prove your answer is correct using points on the graph.​

Answer 1

b and e

Explanation:

Number of days = x

Amount of soda = y

An equation that can represent the relationship between amount of soda and number of days can be represented in the form of y = mx

Where slope (m) = y/x

Using any point on the line, say (1, 40),

m = 40/1

m = 40

Plug the value of m into y = mx

Thus, we have:

y = 40x

This can also be rewritten as:

y/x = 40

Therefore, the equations that can be used to represent the relationship are:

y = 40x or y/x = 40
