PLEASE HELP ME I'LL MAKE YOU BRAINLIEST!!!! In 1972, federal vehicle emission standards 3.4 grams hydrocarbons released per mile
AURORKA [14]
<h3>Answer: Approximately -0.0742857 grams per year</h3>

======================================================

Work Shown:

x = year

y = amount of hydrocarbon emissions in grams, per mile driven

m = rate of change = slope

m = (y2 - y1)/(x2 - x1)

m = (0.8 - 3.4)/(2007 - 1972)

m = -2.6/35

m = -0.0742857 approximately

The approximate rate of change is about -0.0742857 grams per year. The negative rate of change indicates the per mile hydrocarbon amount has gone down by about 0.0742857 grams each year.

Answer:

6

In the y row, it decreases by 1 each time, so 1 decreased from 7 is 6.  To plot this, we take the x and y values from each column and graph it.  For example, the first row would be a point at (3, 8).
