1. FUNDRAISING The Pep Club rented a
shaved ice machine to sell shaved ice as
a fundraiser. They paid an initial fee and
then an hourly charge. The table shows
the cost per hour. Find and interpret the
rate of change and initial value. Assume
the relationship between the two
quantities is linear.
Steps
1) pick 2 points
2) label : (x1, yl) (x2, y2)
y2 - yl
3) Plug into m =
x2 - x1
4) Pick 1 point. Plug in your (x, y) point and plug
what m is into y= mx +b and solve for b.
