Is this right? Examine the rise in gasoline prices from 1997 to 2006. The price of regular unleaded gasoline price in January 1997 was $1.26 and in January 2006 was $2.31 (Bureau of Labor Statistics, 2006). Use the coordinates (1997, 1.26) and (2006, 2.31) to find the slope (or rate of change) between the two points. Describe how you arrived at your answer. Slope is y=mx+b. So I took m= 2006-1997/2.31-1.26= 1.05/9= .116666666= to about .12 cents per year.

To find the slope between the two points, you correctly used the formula for calculating slope, which is:

m = (change in y) / (change in x)

In this case, the change in y is the difference in gasoline prices, which is 2.31 - 1.26 = 1.05.

The change in x is the difference in years, which is 2006 - 1997 = 9.

So, plugging the values into the slope formula, we have:

m = 1.05 / 9

Calculating this division gives us approximately 0.116666666.

However, it seems like you made a small mistake in the final step. Dividing 1.05 by 9 results in approximately 0.1166666667, which is approximately equal to 0.117.

So, the correct calculation of the slope is m = 0.117.

This means that for each year between 1997 and 2006, the price of gasoline increased by approximately $0.117.
