Aski club charges a $45 membership fee plus $18 to rent ski equipment per day. which of the following equation can be used to find the total cost of membership at the club, when renting equipment for x days?

y = 45 + 18x. The $45 is a constant number, and you add $18 for very additional day.

45+(18x)

if x equals the number of days

the required function is .

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.
