I am having a problem with solving slope problems I have tried to work out some of the problem here goes,
According to recycling records kept by the Environmental Protection Agency 38% of postconsumer newsprint was recycled in 1990, 45% in 1992, and 60% in 2001. Written in slope form y = 2.1x + 37
Where y = percent recycled (the percent is not converted to a decimal, so 45% would be enatered as 45 rather than 0.45) and x = the year number coded as 1990 = 1, 1992 = 3, 1994 = 5, and 2001 = 12.
Is the slope positive or negative? what does the slope tells us about the rate of postconsumer newsprint recycling?
45 = 2.1(3) + 37
45 = 6.3 + 37 The slope is positive, and It is increasing at a rate of 6.3 percent a year
Calculate the x-intercept year. What is it and what is the menaing of this point for these data?
5.8 = calculated year,
During what year will recycling theoretically reach 75% according to this model?
in 2004 this is all one question
