A car is moving at a steady rate. The distance it travels is proportional to the amount of time, in hours, it has been driving. It has traveled a total of
168 miles in 3 hours. What is the ratio of distance to the number of hours?
Express your answer as a unit rate with appropriate units.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

using pemdas, (order of operations) you'll see the answer is 24.
