Question 180464: over the years from 1997 when it was $1.26, to 2006 when it was $2,31,gas prices have gone up. Using the coordinates (1997, 1.26) & (2006, 2.31) to find the slope (or rate of change) between the two points. I know that slope or m = y2 - y1 divided by x2 - x1. pls solve and describe how you arrived at answer

You can put this solution on YOUR website! over the years from 1997 when it was $1.26, to 2006 when it was $2,31,gas prices have gone up. Using the coordinates (1997, 1.26) & (2006, 2.31) to find the slope (or rate of change) between the two points. I know that slope or m = y2 - y1 divided by x2 - x1. pls solve and describe how you arrived at answer
-----------------------------------
m = (2.31-1.26)/(2006-1997) = 1.05/9 = 0.1167
