Slope is the rate of change. For us, this rate of change is inches of water per minute. If this rate of change is 2/1, that means that the rate is changing 2 inches every minute (aka The height of the water increases 2 inches per minute, first choice in your list of possibilities).

answer at the state fair there are 36 children standing in line waiting to ride the roller coaster there are 10 cars on the roll

stira [4]

He can put 4 kids in each of 9 cars and then leave the 10th car empty. Or put 2 kids in 9th car and 2 kids in 10th so all the cars would be filled

At a bargain store, Tanya bought 3 items that each cost the same amount. Tony bought 4 items that each cost the same amount, but

babunello [35]

If x is the amount that Tanya paid for each item, then Tony's items would be x-2.25. So:
3x=4(x-2.25)

3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items
