Question

If you rent a car for one day and drive it for 100 miles, the cost is $40.00. If you drive it 220 miles, the cost is $46.00.

Choose the linear equation that would represent the data points

mathmate · Answer

Let
y=mx+b
the slope m can be found by the fact that an extra 120 miles (220-100) costs and extra $6 ($46-$40).
After that, substitute y and x to find b.

Feel free to state this in the question.

anonymous · Answer

A car is traveling at a constant velocity. After two hours the car has traveled 90 miles. After five hours the car has traveled 225 miles. Assuming a linear equation fits this situation, what are the ordered pairs that you would use to find the linear equation?

anonymous · Answer

at least have chooses or something. ?!

anonymous · Answer

(2, 90) and (225, 5) 
(2, 90) and (5, 225)
(90, 2) and (225, 5)

anonymous · Answer

(90, 5) and (5, 225)

anonymous · Answer

those are the choicess
