Answer:
The slope is 3/7 or ~0.43
Step-by-step explanation:
The equation for slope is y2-y1/x2-x1
7-4=3
10-3=7
3/7=0.428
in 1980 it was about 20%
in 1990 it was about 30%
about a 10% increase
in 2000 it was just under 40% so almost a 10% increase
so for estimating you can say it is increasing by about 10% every 10 years
so in 2010 you can estimate about 50% are unmarried
