The average annual cost (in dollars) of tuition and fees at a 2-year college for selected years is shown in the given table, where year 0 represents 2003. The data can be approximated by the equation y = 70.68x + 3112. Predict the average annual cost in 2014 to the nearest dollar.

2005 3261
2007 3388
2009 3540
2011 3681
2013 3826

Answer 1

y=mx+b

Answer 2

I know what the slope format is I just cant write that equation into slope form

Answer 3

since the slope/gradient =0 then the form would just be y=-3

Answer 4

THANK YOU LYNFRAN!!!!
