The average price of a circus ticket from 1970 to 2000 can be modeled by the equation y = 0.32x + 28, where y represents the average price, in dollars, and x represents the number of years since 1970. What does the slope represent ?

The slope means that every year the average price of a circus ticket increases by 0.32 dollars.

Step-by-step explanation:

slope is change in y over change in x

change in average price/years

(-1,-0.5)

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
