Victoria and Roberto write an equation to represent the total amount of money their
team raises, y, based on the number of flights of stairs Victoria climbs, x. Which
statement best describes the equation Victoria and Roberto write?
A The equation is linear because Victoria and Roberto raise some money that
does not depend on how many flights of stairs Victoria climbs.
B.
The equation is linear because the amount Victoria and Roberto raise increases
at a constant rate for each additional flight of stairs Victoria climbs.
