Question 1030431: Hello, I have a confusing question that I have been trying really hard to understand. You see, its a table. It goes like this:
School Year /x /Cost /Increase
2000-2001 / 0 /$10,820/ ?
2001-2002 / 1 / $11,380/ ?
I'm having trouble finding the increase in tuition. The problem goes "Calculate the increase over the previous year for each school year and put the value in the table. Then it asks to write an equation. I've tried doing y=mx+b or adding the first set of years, multiplying by 0 and adding the cost to find increase. But I doubt that I did it correctly
Your help would be greatly appreciated and I'd be so grateful to have an understanding of the math! Thank you so much!

--------
Increase in 2000-2001:: 0
Increase in 2001:2002:: $560
---------
y = mx + b where x is the number of years after 2000-2001
----
f(0) = 10820
slope = (11380-10820)/(1-0) = 560
---------------------
Equation:
y = 560x + 10820
