Some consider that the salon stylist offers something more than other types of services, because the salon stylist  knows our hair,  realizes with us a more intimate relationship, than for example, a waiter, because salon stylist keeps our hair, knows our damaged parts of hair, know how to correct it and so on. Again, according to unofficial rules, more than 20% should be given if we are late for the scheduled term, etc.

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
