Before I write my question I want to make it clear that I am not looking to cheat. I simply need help with a few question and I don't need an comments not focused on that. Thank you :)

3: What's the slope?

Number of Miles Total Cost ($)
0 3.00
1 4.75
2 6.50
3 8.25
What does the slope mean in this situation?

Don't want to sound impatient but I really need to get this done :)

the slope is ∆y/∆x

Since ∆x = 1 in this table, the slope is just the change in y for each interval
Looks like 1.75
