Respuesta :

The proportional equation that represents the situation is:

y = 13x

What is a proportional relationship?

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

[tex]y = kx[/tex]

In which k is the constant of proportionality, also called slope.

In this problem, the points (number, cost) are: (3,39), (5,65) and (8,104), hence the slope is given by:

[tex]k = \frac{39}{3} = \frac{65}{5} = \frac{104}{8} = 13[/tex]

Hence, the equation is:

y = 13x.

The slope of the linear equation is $13 per necklace.

Linear equation

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope (rate of change), and b is the y intercept (initial value of y).

Let y represent the total charge for x number of necklaces.

From the table, using (3, 39) and (8, 104), hence:

m = (104 - 39) / (8 - 3) = 13

The slope of the linear equation is $13 per necklace.
