Question 124753: According to recycling records kept by the Evironmental Protection Agency 38% of postsonsumer newsprint was recycled in 1990, 45% in 1992, 47% in 1994, and 60% in 2001. written in intercept form is
y = 2.1x + 37
where y = percent recycled (the percent is not converted to a decimal, so 45% wold be entered as 45 rather than 0.45) and x = the year number coded as 1990 =1, 1992 = 3, and 1994 = 5, and 2001 = 12
Is the slope positive or negative? What does the slope tell us about the rate of postconsumer newsprint recycling?

Is the slope positive or negative?
Ans: The slope is 2.1 which is positive
-------------------------------------------
What does the slope tell us about the rate of postconsumer newsprint recycling?
It is increasing at a rate of 2.1% per year.
