Question

A 3-mi cab ride costs $3.00.A 6-mi cab ride cost $4.80.Find a linear equation that models costs c as a function of distance d.

Answer 1

y=mx +c
where y is cost
x is dist
m and c const
now
3= 3m +c
n
4.8= 6m+c
solve them to get
m=0.6
and c=1.2

Answer 2

so it would be c=0.06d+1.20

Answer 3

meaning for every mile the rateincreases by 0.6$ (hence it increased from 3 to 4.8 for 3 miles increase
and the cost at the beginnin is 1.2 $
