Answer:
The slope is 3 or 3/1.
Step-by-step explanation:
The amount of money will always be counted as a y value. So, you can do 345 - 255, which is 90, over 120 - 90, which is 30. You will have 90/30, that will simplify to 3 or 3/1. Therefore, your slope is 3.
There are 1600 metres in 1 mile, so 10095÷1600= 6.3 miles/s
48/4 is 12. 3*12 is 36. So Hayden has 36 new baseball cards.
