The graph shows how many bottles a machine caps in a certain number of seconds shown in the picture below Part A What is the constant of proportionality and wha class=

Respuesta :

Considering the proportional relationship graphed, it is found that:

A. The constant is of 20.

B. A pair on the graph is given as follows: C. ) (45, 900); the machine caps 900 bottles in 45 seconds.

What is a proportional relationship?

A proportional relationship is a linear function with intercept zero in which the output variable y is given by the multiplication of the input variable x and the constant k, as follows:

y = kx.

Considering point (15, 300) on the graph presented, the constant is calculated as follows:

300 = 15k

15k = 300

k = 300/15

k = 20.

The input and the output are given as follows:

  • Input: number of seconds.
  • Output: number of bottles capped.

Hence option C is the correct option for item 2.
