document.write( "Question 410676: The linear equation y=0.15x+0.79 represents an estimate of the average cost of gas for year x, starting in 1997. The year 1997 would be represented by x=1, for example, as it is the first year in the study. Similarly, 2005 would be year 9, or x=9. What is the slope (or rate of change) of this equation? \n" ); document.write( "
Algebra.Com's Answer #288736 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! Slope is 0.15 since it is already written in slope-intercept form. With the units the slope would be $0.15/year. \n" ); document.write( " |
