Marc gets paid $15 per lawn he mows. Graph the proportional relationship. Determine the slope and what it means in the context of the problem. How can the slope be used to determine how many lawns Marc mowed if he made $180? What is the equation that describes the relationship between the two quantities?

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

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.
