a 2mi cab ride costs $4.25. a 7mi cab ride costs $8.50. which equation models the cost y of a cab ride that is x miles?

a+2b = 4.25
a+7b = 8.50
(a,b) = (51/20,17/20)
so,
y = 2.55 + .85x 
. Which ordered pair could you remove from the relation {(–2, –1), (–1, 1), (–1, 0), (0, 1), (1, 0)} so that it becomes a function?

The time t required to drive a certain distance varies inversely with the speed r. If it takes 2 hours to drive the distance at 30 miles per hour, how long will it take to drive the same distance at 50 miles per hour?
