jessica is selling books during the summer to earn money for college. she
earns a commission on each sale but has to pay for her own expenses.
after a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
she writes the equation of the function like this: e(x) = 10x-30, where x is the
number of doors she knocks on during the week and e(x) is her earnings for
the week in dollars.
which of the following are reasonable interpretations of the y-intercept of
jessica's function?
check all that apply.
