You have the coordinates (5,3.2) and (9,4.2)
Propose a linear solution of
where
C = cost of fair
d = distance travelled
a = the rate per kilometre travelled
b = flagfall amount
using (5,3.2) to find b
so we have
ok so i have a solving problem about substitution
Taxis in a certain city charge a flat fee plus an additional charge per kilometer. Russ was charge $3.20 for a 5-km ride and Kylie was charged $4.20 for a 9-km ride. Someone lay out the 2 equations since i can't seem to figure out the two equations?
