The manager of a weekend flea market knows from experience that if he charges a dollars for a rental space at the flea market, then the number y of spaces he can rent is given by the linear function y = f(x) = 60 -6.x, x < 10. Which of the following statements are true? A. The y-intercept of the graph of f is 10 and this is the number of spaces that would be occupied if there were no charge for each space. B. The x-intercept of the graph of f is 10 and a $10 rental fee results in no spaces being rented. C. The slope of the graph of f is -6 which means that for each increase of $1 for a rental space, the number of spaces rented decreases by 6.

Which of the following statements is true?
The manager of a weekend flea market knows
from experience that if he charges r dollars
for a rental space at the flea market, then the
number y of spaces he can rent is given by the
linear function
y =
f(x) = 60-6x, x 10.
f(x)
Which of the following statements are true?
A. The y-intercept of the graph of f is 10
and this is the number of spaces that would
be occupied if there were no charge for each
space.
B. The x-intercept of the graph of f is 10
and a $10 rental fee results in no spaces being
rented.
C. The slope of the graph of f is -6 which
means that for each increase of $1 for a rental
space, the number of spaces rented decreases
by 6.
